In "Bad Scare Day", Hackington served lunch in the creepeteria when Frankie Stein, who had accidentally put in her bolts wrong, making her a walking electromagnetic disaster, entered. All the iron-containing kitchenware flew right out of Hackington's hands and past him until Ghoulia Yelps fixed Frankie's bolts.

In "Freedom Fight", Hackington intended to have his class dissect a number of three-eyed frogs. Lagoona Blue objected to this, believing it to be cruel. She asked Frankie Stein to create a diversion so she could steel the frogs and bring them somewhere safe. Frankie had fer left hand tickle Hackington and start an eyeball fight, bringing about a chaos that didn't end until the class was over. Hackington grudgingly accepted nothing would be cut open that day.

In "Freakout Friday", Hackington was one of the many to fall victim to bad luck. In his case, he stepped on a crack, breaking his mother's back.

In "Hatch Me If You Can", Hackington showed up with a cyclops assistant and a number of eggs that he distributed to couples of students with the order to take care of them for one week. If the eggs so much as showed a crack by then, the two responsible would fail the test. Peculiarly, he suggested that Lagoona and Gil would chose other partners, because "everyone knows that sea creatures are bad parents". This made the two determined to prove Hackington wrong. By the end of the week, Hackington noticed a crack in their egg and told them they had failed. Lagoona and Gil didn't understand until their egg started to shake. Hackington quickly asked his assistant where the eggs came from, to which he casually replied: "Gargoyle nest at the top of the library." The egg hatched a moment later and the gargoyle baby attacked Hackington.

In "Fear-A-Mid Power", Hackington sold blood sausages during a game of casketball.

In "Screech to the Beach", Hackington drove the bus that brought a large portion of the Monster High student body to Gloom Beach. Upon Cleo de Nile's request he'd bring their bags into the nearby hotel where all the other students stayed, Hackington happily informed her the fearleading team would be staying a little farther away, in a badly maintained cottage.

Mr. Hackington was beset by a plague of frogs in "Queen of the Scammed".

Hackington ran up the stage in "Desperate Hours" to hand Rotter a letter about Toralei Stripe's, Purrsephone's, and Meowlody's incredible math grades and their arranged trip to math camp.

Mr. Hackington has his students work on a chemical experiment that requires the solution to be heated slowly. Heath Burns isn't patient enough and heats his solution faster, causing a scargoyle to appear and cover him in eyeball goo. Later, Hackington catches Howleen Wolf assaulting the Belfry Prep vampires with garlic, for which he sends her to Headless Headmistress Bloodgood's office.

Volume 3
