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, Cleo helps Frankie put together a tape to sent in. As luck has it, they win the contest. Cleo participates in Monster High's 1361st Annual Charity Talon Show. One of her competitors is Clawdeen, who takes the stage just after her. Cleo attempts to sabotage Clawdeen's performance by turning on the spotlight, which works as a substitute full moon on her. She loses control, but rather than it being disastrous, she improvises her way through a killer dance that easily beats Cleo's. Cleo is hosting the fearleading try-outs and is busy explaining the high demands of the Fear Squad to the candidates when Frankie bursts in. The simulacrum's hand becomes detached, and Frankie performs several difficult moves to get it back, earning herself a spot on the Fear Squad despite Cleo's objection. Cleo'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 Cleo and the other students consider the class dismissed. When Clawdeen shows up unprepared for the SAT that day, Cleo advises her to copy Ghoulia's answers. Cleo is annoyed that Draculaura dares suggest her crush is hotter than Deuce and tries to sabotage her chances. Cleo advises her to touch up on her makeup first and offers to do it for her. Rather than making Draculaura prettier, however, Cleo makes her look horrendous. Amazingly, Heath digs the look, so Cleo's plan is foiled and Draculaura gets her date. Cleo has her locker door smash closed on her by Frankie's haywire charge, causing her earrings to become stuck in its vent. It's Picture Day, but Coach Igor's covering Study Howl and he's obsessed with sport. Cleo and her friends make 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. When Frankie develops a zit on her cheek, Cleo makes sure to take a picture and send it to all students. Irony strikes when she herself becomes covered with zits. Cleo vies to be the leading lady of the school's production of Hamlet, but Clawdeen is her main rival. The two sabotage each other's auditions to the point they both end up in plaster while Draculaura gets to be leading lady.

An eyeball fight breaks out during Biteology and Cleo participates. She is later chased out of the girls' bathroom by a frog infestation.
