The festival celebrates the shedding of skins that each monster must undergo as he or she moves from childhood to adolescence. As the festival approaches, Krumm is chosen to form a band and Oblina is chosen to perform the festival's ceremonial dance. Ickis, who shows no signs of shedding, feels left out.

Ickis, Krumm, and Oblina sneak into Simon's house to scare him. After the scare, Simon seems to know the monsters' whereabouts. He shows up when they least expect it. How is he doing it?

Oblina, overstudying for an upcoming exam, sneezes her brain out of her head. While the brain has the time of its life in the city, Ickis and Krumm must take Oblina's body and find the brain.

Ickis, Krumm, and Oblina go on a scare in an abandoned building. They spot four gargoyles, monsters condemned to live out their days in cement for a crime they claim they did not commit. Ickis frees them from their prison, but soon has to run for his life when he discovers they are guilty of the crime.

Ickis discovers a remote control helicopter in the dump and uses it to scare humans from long distance. Zimbo hates the helicopter because he feels there's only room for one flying monster in the Academy. Soon he and the "Ickis Copter" get into a dogfight!

When the Gromble dumps his obnoxious nephew on Ickis, Krumm, and Oblina, the only way they can find to keep him quiet is to tell him a story. Oblina treats the tyke to her own version of "The Three Billy Goats Gruff" where the Troll is the hero.

Ickis, Krumm, and Oblina are saddled with babysitting the Gromble's nephew, Bomble. They take him along on a garbage hunting trip to a local hospital where the baby monster is accidentally switched with a new-born human baby. The trio must track down the Bomble at the home of his new human ""parents"" and replace him with the human.

A new carnival opens near town and The Gromble is insulted and outraged by one of its attractions - the ""Monsters Are Fun"" ride. He assigns his two top students, Oblina and Krumm, the task of scaring its riders and shutting down the attraction.

Ickis is in the middle of projecting a botched scare on the viewfinder when The Gromble sees something on the screen that makes him turn white as a sheet-- the red delivery van of Dick Jolly of "Jolly Rooter Sewer Service." Years earlier The Gromble tried to scare Jolly but was thwarted by Jolly's horrible "sewer eater" (the Roto-Rooter machine). The Gromble takes Ickis, Krumm and Oblina on a misguided search for Jolly.

Oblina is left in charge when the Gromble goes off to the Annual Academy Teachers Convention, and power goes to her head.

Ickis, Krumm and Oblina go for a romp in the sewer, tossing one of Krumm's eyes around in a game of catch. The eye accidentally falls into the water and is swallowed by a boa constrictor. The snake leads the trio on a a wild chase. It eventually ends up at a rock concert, where they finally capture it, along with Krumm's eyes.

When Oblina is invited home for the weekend, Ickis and Krumm come along and discover that being rich is no walk in the dump. Krumm and Ickis have to convince Oblina to stand up to her domineering mother after she insists that Oblina must leave the academy and return to the estate for good.

Krumm misplaces an eyeball for the seventh time in a week, and decides what he really needs is a head. Oblina refers him to a monster plastic surgeon, who gives Krumm the head of his dreams. It's big and square - and Krumm tops it off with an orange rug.

Ickis' boasting gets the better of him after he sits through a cutesy movie, just to prove that he can. The movie doesn't give him bad dreams, but Zimbo does, when he dresses as the main character and begins to torment Ickis.

Ickis, Krumm, and Oblina pick a seemingly mild-mannered Englishman to scare, thinking it will be a piece of cake. The trio soon discover the scare is not as easy as it looks. The Englishman is a secret agent, dodging danger at every corner.

A wacky radio DJ announces that $50,000 has been hidden in the dump. Soon humans are swarming there and the monsters can't get rid of them. Ickis, Krumm, and Oblina find the DJ and scare him, getting the humans out of the dump by announcing the money is at the radio station.

Ickis, Krumm, and Oblina discover an old movie in the dump, which they watch constantly despite the Gromble's protests. They begin to ape the characters in the movie and even try some dangerous cowboy movie stunts in their scaring.

Ickis falls head over heels in love when he spots the screeching hook-nosed Judy from a street corner Punch and Judy show. Not knowing she's a puppet, Ickis finally shares his feelings with his friends, who help him to present himself to the object of his desire.

Ickis is given the job of polishing The Gromble's sacred "Amulet of Enfarg", a medal given to the most honoured of monsters. Ickis gets so caught up in his daydream of one day being awarded the Amulet that he wears it to a group scare at a department store, and loses it.

When Krumm loses his pit hairs as the result of a "Monster Mischief Day" prank, Ickis vows to do anything to get him his hair back. Ickis finds a stash of discarded "Super Grow" hair tonic in the dump and rubs it in Krumm's pits--to disastrous results.

When Ickis runs away from the Academy he falls in with an old bluesman who cannot be scared because he's blind. The two become friends as the bluesman teaches Ickis a thing or two about being your own man -- or monster. Ickis returns the favour when he scares the demolition crew that arrives to destroy the old man's building.

The Snorch, tired of not being able to communicate, gets a new voicebox installed by Dr. Buzz Kutt which gives him a beautiful speaking voice. Oblina, impressed by his intelligence and eloquence, shows him how to scare and they become fast friends - leaving Zimbo, Ickis, and Krumm out in the cold.

A new transfer student arrives at the dump. The Skrink is a small, shy fellow with odd noise-making appendages. Ickis is paired with The Skrink for "pair-scaring", but isn't happy.

The Gromble is up of his job review at the hands of Balook The Granfaloon, a puny, "by the book" Bureaucrat, who fires The Gromble for breaking a trivial rule against students celebrating after a scare.

Ickis, Krumm and Oblina are bored. Oblina has the bright idea to organise a slumber party. Girl monsters only. Ickis, Krumm and their friends, with nothing better to do, decide to sabotage the girls' night.
