Even as a new student at Monster High, Frankie is full of initiative. When Radio KBLOOD announces a contest of which the prize is that the Jaundice Brothers come play at the winner's school's homecoming dance, Frankie gets the entirety of Monster High to help put together a tape to sent in. As luck has it, they win the contest. Frankie, Lagoona, and Draculaura attend Monster High's 1361st Annual Charity Talon Show to root for Clawdeen, who gives a killer performance. In a hurry for a shortcut to Home Ick, Frankie bursts in on the Fear Squad's tryouts. She trips over a barbell and loses her right hand, thus forcing her to chase after it. In doing so, she performs several impressive moves and is promptly made a member of the squad. Frankie's Trigular Calcometry 101 class is hosted by a substitute teacher, Lou Zarr, who does not get along with the class. A conflict with Deuce leaves him petrified, upon which Frankie and the other students consider the class dismissed. Frankie realizes it's Draculaura's Sweet 1600 and plans a surprise party for her, forgetting it is her own Sweet 16 (days) too. However, none of her friends can come to the party. Frankie sadly makes her way to the creepateria for lunch, where she bumps into Draculaura. It turns out that Draculaura was planning a surprise party for her all this time, but that didn't work out either, so the two friends agree to hold a party for just the two of them. As they open the doors to the creepateria, though, they are met by all their friends who were arranging a surprise party for the both of them. During Clawculus, Frankie, Clawdeen, and Draculaura try to get Lagoona to talk to rather than stare at Gil, a boy she likes. Frankie is one of the people Clawdeen confides to that she hasn't studied for the SAT. Witnessing Cleo accidentally do something nice for Draculaura, Frankie compliments her. Following a collision with Mr. Where in the hallways, Frankie plugs her bolts back in on the wrong ends, reversing her polarity and making her charge go haywire. The situation escalates in the creepateria, but fortunately Ghoulia has deduced what's wrong and fixes Frankie's problem. It's Picture Day, but Coach Igor's covering Study Howl and he's obsessed with sport. Frankie is dragged along by her friends on a looks-destroying escape from a looks-destroying workout, though Igor eventually catches up to tell them they won't have run lapses because of Picture Day.

Ghoulia has her eyes on Slo Mo, but is too shy to talk to him. Frankie, Clawdeen, and Draculaura offer to help her out, but their aid is of such quality that Ghoulia timely decides to go with her own instinct. Frankie develops a zit on her cheek and walks around the school with a paper bag over her head until the Fearasil Ghoulia put on gets it gone. Frankie auditions for a role in the school production of Hamlet. Lagoona is highly upset that Mr. Hackington is about to dedicate that day's class to dissecting frogs. As such, she gets Frankie to create a diversion, while she saves the frogs. Frankie does so by detaching her hand, which crawls up Hackington and tickles him as well as starts an eyeball fight in the classroom. Following a collision with Frankie in the hallways and Cleo's subsequent struggle to get loose, which resulted in a statue being knocked over and broken, the two girls are ordered to Headless Headmistress Bloodgood's office. There, Cleo puts all the blame on Frankie. Bloodgood accepts this and then informs Frankie that breaking the statue was a good thing because one of Monster High's first teachers had been locked inside of it for millennia. Frankie readily accepts the praise, much to Cleo's regret. It is both Friday the 13th and Halloween, a rare occurrence that spells bad luck galore until three o'clock. Frankie and her friends panic, but Cleo assures them that her amulet will protect them. However, Ghoulia's carrying the amulet and she just walked off. The girls chase after her to be safe, only to find her use the amulet to get to the big clock and adjust the time to three o'clock. Frankie and Lagoona attend the Mad Science Fair, where they find Cleo to have stolen Ghoulia's project. They try to get her to get it back, but Ghoulia declines. Cleo wins the fair and claims the 'throne', which actually is Lagoona's project: a rehydration chamber. Lagoona dunks Cleo, then hands Ghoulia the remote of the rehydration chamber. When Frankie's friends discover she's never seen a movie, they promptly take her to the auditorium to watch the entire TwiHard series. In preparing for the movie session, they overtax the room's electricity net. To solve this, the group hooks up the equipment to Frankie, allowing the movie session to go through but Frankie not to watch anything. It is discovered that vampires have the ability to turn into bats and Frankie and Clawdeen ask if Draculaura can show them. Draculaura lies she can, but not in front of them, so she leaves to the belfry where she falls asleep and a bat flies down into the school. Frankie and Clawdeen mistake the bat for Draculaura and spend a great day in its company. Frankie gets a text from Draculaura instructing her to send it along to anyone. Because she's walking while texting, Frankie bumps into a fountain which brings out her charge which in turn causes alterations to the text before it's sent through.

Draculaura has a chance to meet her perfect guy, but she has to get into contact with him before school's out. Frankie attempts to stop him by shocking him, but he recovers swiftly. Lagoona and Frankie greet each other in the hallways. Ghoulia is invited to share lunch with Slo Mo, but she's scared, so Frankie offers to accompany her. However, Heath Burns also sits at the table and won't stop hitting on Frankie. Frankie retaliates by getting Heath to sit under a fire sprinkler, which Heath promptly activates to the amusement of many. Frankie has her first sleepover at Clawdeen's house, where Cleo tries to manipulate Frankie into spilling whom she's crushing on through a game of Truth or Scare. Frankie chooses truth and is ordered to send a text reading "party at my house", which she does. Cleo is amused only until she realizes the text was sent on her own cellphone. To help Lagoona with an unexpected parent-teacher conference, Frankie, Cleo, and Clawdeen dress up Slo Mo as Lagoona's aunt Lantic so he can figure out what the conference is about.

TV specials
In the first TV Special, New Ghoul @ School, Frankie is narrating her first week of classes at Monster High.

Monday, she tries to make a good first impression on the other students, but fears she will stay a loner during her time there.

Tuesday, she goes to class with Mr. Lou Zarr, and meets Cleo De Nile, Ghoulia Yelps, and Draculaura. She later meets Clawdeen after she saves Frankie and Draculaura from a zombie flesh mob.

Wednesday, Frankie attempts to join one of the school clubs, but all her efforts fall flat. She does not even study the rules of Chess for Chess Club, electricutes the Swim Team, and ruins Cleo's hair when she hands Cleo a pencil to sign Frankie's petition that Frankie had no idea she was accepting signatures for until Cleo told her. Joining the Fear Squad was Frankie's last hope, only to see that Cleo is the head Fearleader, and Frankie's attempts to repeat the Fear Squad's performance causes her foot to come loose and land in Ghoulia's drink, splashing Cleo, and causing her to emit a scream loud enough to shatter glass. Devastated and embarrassed, Frankie flees to the pool, where she is comforted by Lagoona, who offers some friendly advice about just being yourself. Later on, Clawdeen and Draculaura tell Frankie that Cleo wishes to interview her for the Fear Squad tomorrow morning. Frankie completely forgets Lagoona's advice, not noticing Lagoona watching with disappointment at Frankie attempting to get into the Fear Squad without taking her advice to heart.

Thursday, Frankie meets up with Cleo in the cafeteria for the interview, and despite Cleo's rapid-fire questioning, when Frankie mentions Justin Biter as her favorite singer, it looks like she and Cleo are on good terms now, only for things to go up in flames when Frankie names Deuce as her boyfriend, enraging Cleo at the thought that Deuce was cheating on her. Frankie flees to the pool, but not even Lagoona is on her side now after seeing that Frankie completely abandoned her advice. Cleo is there as well, and orders Frankie out of her life, never wanting to see her again.

Friday, with how the week went, Frankie makes it clear that she needs to make amends with everyone she's met at Monster High. She first apologizes to Draculaura and Clawdeen, and asks for their help with making amends with Cleo. She then explains everything to Deuce, and together, they meet Cleo outside the gymnasium. Frankie explains everything, repairing Cleo and Deuce's relationship, but Cleo is still unforgiving to Frankie for what happened. Frankie then reveals she was able to get Justin Biter to perform a special concert at Monster High to repay a favor he owed the Steins. Thanks to that, Cleo forgives Frankie and accepts her into the Fear Squad, but on probation.

Frankie is fine with that since her first week of Monster High ended with her making several friends that will be at her side from here on out.

Frankie is still on probation and undeniably the weak link of the Fear Squad. Nonetheless, she is the only member of the team not to desert in protest of Cleo's leadership. Being the only one left, Frankie asks to be taken off probation, which lasts only until she spills a drink on Cleo in her enthusiasm. With the Fear Squad try-outs a failure, Frankie decides to recruit on her own. Most people she approaches run away, so she tries her friends. With a bit of manipulation, Clawdeen and Draculaura join the Fear Squad. Cleo is unhappy with the new Fear Squad's performance yet and orders them to attend every school event for the time being to gain experience. All of their cheers have disastrous consequences for the school's performance, but they keep trying. Good-natured as always, Frankie tries to pep her teammates for the Spirit Rally, but doesn't have much success. Frankie tries to keep the Fear Squad's spirits high and comes up with various theories as to why Cleo is not with them. The Fear Squad performs the cheer without her, but blunders at the end. Fortunately, their failure is forgotten about as soon as it is time to dance. Denied for Gloom Beach, Frankie informs the team they still have a chance if they go for the wildcard arrangement: create a fearleading video and get it a million hits on FrightTube in two days. Though the odds are low, the Fear Squad imediately gets to work. The Fear Squad's video has barely gotten any hits, so the team tries to promote it. With Ghoulia's help, they manage to lure in a big audience and reach 999,999 hits. However, FrightTube chooses that moment to crash. The Fear Squad anxiously looks on as Ghoulia tries to do something about the crash. Despite her best efforts, the clock strikes 3:00 PM before she succeeds. Cleo tearfully thanks her friends for all they've done, but the mood is promptly improved when Deuce delivers the news that FrightTube crashed because of all the traffic to their video. Rather than a million hits, they've got twn million hits. Their Gloom Beach invitation follows soon after. During the ride to Gloom Beach, Frankie has a dream of becoming the captain of the Fear Squad. She awakes when the bus arrives, only to find that the Fear Squad will be staying in a decrepit cottage. When Scary Murphy hands the Fear Squad a list of chores to do, Frankie reluctantly and skeptically goes through them.

After finishing the chores, the Fear Squad relaxes at the beach while Cleo and Ghoulia work out a routine. The Fear Squad gathers at dusk to memorize the routine but they are watched by the werecats. Toralei later steals Frankie's recording of the routine and hands it to the Smogsnorts team. It is discovered only at the competition that the werecats stole the Fear Squad's routine and gave it to Smogsnorts. Cleo uses the movements from the chores Scary Murphy had them do to improvise a new routine, which wins them the spirit staff. Frankie and the rest of the Fear Squad have become a target of revenge for the werecats. First they are splashed with water just as a fearbook photo is supposed to be made, and then Cleo is tricked into agreeing to stay at Monster High on the night of Friday the 13th. Frankie joins Cleo in spending the night of Friday the 13th at Monster High. They encounter a monster roaming through the school, but it turns out to only seek people to celebrate its birthday with. During lunch, the topic moves to relationships and Frankie lies she has a boyfriend. Her Frankie want to meet him, so Frankie brings a life-sized voodoo doll to school the next day that she thinks she failed to bring alive. Weirded out, her friends assure her she does not need a boyfriend to fit in. Frankie happily puts the doll with the trash, only to discover he is alive. Frankie rushes to Draculaura's aid when she faints at the sight of a steak. She gets her to the bathroom for recovery, where Clawdeen later enters to apologize to Draculaura for the steak. Frankie runs all across school to get everyone's signatures for her fearbook copy. She is with Draculaura when Toralei hands her a paper she supposedly dropped, which contains a recipe for stinkbombs, just as Mr. Rotter walks by and overhears. Ghoulia has discovered that the werecats are behind the odd events of the day. Her friends thus confront the trio and learn that they plan to pin the blame of a stinkbomb on the Fear Squad so that they'll get expelled. The group rushes out and collects the bomb before it drops.

In the special, Why Do Ghouls Fall In Love?, Frankie finds herself caught in trying to save Draculaura when a plot set up by a jealous Torelei with an old flame of Draculaura's from Transylvania, Valentine, plans to leave Draculaura heartbroken on her Sweet 1600th birthday. When one attempt by C.A. Cupid results in Cupid falling in love with Clawd due to Torelei's intervention, it is only during Draculaura's party that Frankie, with help from Lagoona and Abbey, are able to recover Cupid's bow and break the spell on everyone, giving Clawd the chance he needs to break Valentine's spell on Draculaura, and leave Torelei and Valentine to be ejected from Draculaura's party by Cleo's Egyptian bouncers after falling in the Pit of Eternal Body Odor.

In the special, Escape from Skull Shores, Frankie is joining her friends on a visit to the Great Barrier Reef in Austrailia to visit Lagoona's parents during Spring Break from Monster High. When a kraken destroys their ship and leaves them adrift, an eccentric salesman by the name of Bartleby Farnum, rescues them and takes them to Skull Shores, secretly under the surmise that Frankie will lure out the beast that Farnum is searching for on the island. Frankie is soon taken by said beast, only for the beast to be a young, teenage monster by the name of Andy, who becomes his monstrous, beastly self when experiencing negative emotions like anger, hate, and fear, be it from himself or another. The reason he kidnapped Frankie is because she looks so similar to a young girl Andy met a long time ago, who was not scared of him at all. He had made all the stautes Frankie has seen around the island to remind him of her and keep him from assuming his beast form. When Farnum takes Frankie hostage and threatens to drain her electricity, Andy transforms and surrenders to Farnum, only for Farnum's plan to fail when Gil arrives with the kraken to sink Farnum's boat and return the students' repaired boat so they can return home. Frankie is able to convince Andy to leave Skull Shores with them and return to Monster High.

However, Farnum launches another attack at the school sometime after Andy has enrolled and is still adapting to modern technology due to his isolation on Skull Shores. When Farnum pushes Andy to transform again, Frankie holds her ground to try and talk him out of it, but he takes her and climbs to the top of the school. Once there, Frankie's further attempts to help Andy fail as he once more surrenders to Farnum, only for Farnum to then be betrayed by his assistant, Kipling, leading to Farnum being tar-and-feathered, and hauled away to a psych ward by a couple of humans who he had called to capture Andy.

Like with Andy, Frankie convinces Kipling to stay at Monster High as well, and when Headless Headmistress Bloodgood extends Spring Break another week to deal with repairs to the school, Frankie joins everyone else as they return to Skull Shores to enjoy their extended Spring Break with the Tikis.

In the Halloween special, Ghouls Rule, Frankie is about to enjoy her first Halloween at Monster High, but soon learns of the hostility between the human students at New Salem High, and the monsters of Monster High. At one point, she finds the long lost Hall of Halloween, and attempts to re-teach the true meaning of the holiday to everyone, but gets caught up in the events being orcestrated by Lilith Van Hellscream and her cronies and Cleo to keep the hostilites flaring between humans and monsters. When Jackson Jekyll/Holt Hyde is exposed by Lilith to the New Salem Sheriff, he plans on executing Holt with the Trick-Or-Treatment. With Headless Headmistress Bloodgood ordered not to intervene by the Monster Elder Council, Frankie tries to save Holt by getting Cleo and Lilith to confess to the Sheriff, but he refuses to release Holt under the surmise of wanting to prove he's a capable lawman. As a result, Frankie joins forces with Lilith and several other New Salem students she befriended, to rescue Holt, and lure the New Salem kids to the Hall of Halloween to show them the true spirit of Halloween. When the Sheriff and his officers arrive to arrest not only Holt, but Frankie and the other Monster High students as well, Lilith and the New Salem students protect them, forcing the Sheriff and his men to stand down and join the festivities.

Frankie ends the special with how she was able to help restore the true meaning of Halloween back to both Monster High and New Salem High, and then joins everyone in dancing before a final shot of Frankie and her friends in their Ghouls Rule attire.

In the TV Special, Freaky Fusion, Frankie finds herself struggling to find information about her family for a project for Mr. Rotter, but her parents withhold telling her anything, and she knows little about her grandfather, Victor Frankenstein.

During an incident that transports her, Ghoulia, Torelei, Cleo, Draculaura, Clawdeen, Lagoona, Jinafire, Robecca, and Venus to 1814, they see Robecca's father, Hexiciah Steam, as a former professor at Monster High, and a young, intelligent student by the name of Sparky. Sparky is trying to find that critical spark to create life, but continues to fail due to his lack of patience. When Sparky follows them back to Hexiciah's lab, he damages the time portal they came through, causing eight of Frankie's friends to be accidentally fused together into freaky hybrids of themselves as they return to 2014. Frankie and Ghoulia are unaffected since they went through individually, but the others have become Clawvenus(Clawdeen and Venus), Dracubecca(Draculaura and Robecca), Cleolei(Cleo and Torelei), and Lagoonafire(Lagoona and Jinafire).

While Ghoulia tries to fix the portal, Frankie turns to the new, hybrid students that just enrolled in Monster High for help with getting her friends accustomed to their new forms. With the aid of Avea, Sirena, Bonita, and Neighthan, Frankie's friends gain better control of their hybrid forms, and a romantic relationship seems to develop between Frankie and Neighthan.

Tragedy strikes when the play that Frankie and her friends were putting on about Monster High's history is interrupted by Creation 4.0, the latest attempt by Sparky to create life after he was brought to 2014 by accident as well and attempted to try again using modern technology. When the monstrosity captures Frankie's freaky fused friends as it's prisoners, the overwhelming emotional reaction Frankie endures causes the very essence of the spark of her life force to manifest physically for her to use to electrocute Creation 4.0 and free her friends, defusing them in the process, but also taking a heavy toll on Frankie as well. Despite her suffering, she refuses to quit even after freeing Cleo, Torelei, Clawdeen, Venus, Lagoona, and Jinafire, as she uses every ounce of energy she has left to save Robecca and Draculaura, and shut down Creation 4.0 for good, but leaving her fatally drained as well. Guilty over what he's done, Sparky apologizes and reveals his true name to be Victor Frankenstein, Frankie's grandfather. Frankie dies happy at having gotten to meet her grandfather in person before she passed away.

Despite the tragedy, Victor attempts to redeem himself by trying to revive Frankie, but it takes the spark of joy that Frankie has brought to everyone at Monster High, friends and fellow students alike, that is able to bring her back from the dead, while also changing her physical appearance as well. With her green eye now yellow, and streaks of blue, green, and yellow in her black hair along with a matching dress to boot, Frankie is revived, and following after Victor and Hexiciah return to 1814, Frankie's parents come clean and tell her everything about the family history.

Thanks to those events, Frankie's second attempt at her project for Mr. Rotter scores her an "A" for a wonderful job, and she ends the special at having helped to show that no matter who your parents or family are, you can make a difference in helping to show how important family and friends are in your life.
