Wanting a face only a monster could love, Ickis contemplates plastic surgery. John Astin guest-stars.

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.

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.

Every boy and monster's worst fear is realised for the Gromble -- his mom shows up at the academy unannounced. The Gromble leaves her in the care of Ickis, Oblina, and Krumm for the afternoon with alarming results.

Ickis gets "flashed" (gets his picture taken) by a celebrity reporter. If this picture runs on the front page, monsters' existence will be revealed to humans. Our heroes must band together and go above ground to retrieve every newspaper copy before dawn.

Ickis, Oblina, and Krumm are bored when Gromble's old teacher lectures at the academy. But when they escort him back to the dump, they learn that old monsters are the best monsters.

Feeling like Ickis and Oblina are not paying him enough attention, Krumm moves out of their dorm room and into the room of two other monsters - Snav and Blib. These two monsters spoil Krumm with attention, which he needs - at first. But soon Krumm realises that being the centre of attention is not all it's cracked up to be.

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, Krumm and Oblina get trapped inside a nuclear power plant when they accidentally set off a warning device closing down the entire facility. Seeing the three monsters on a monitor, one of the plant workers mistakes them for three plant employees. A team of highly trained doctors don protective clothing and go inside the facility to bring the "employees" out to safety.

Ickis, Oblina and Krumm pull off a good scare in Bradley's room, only to discover that Ickis has left his all-important monster manual on the surface.

While getting ready to do a scare at a hypnotist's show, Ickis stares at the hypnotist's watch and inadvertently gets hypnotised along with the hypnotist's intended subject - a loud-mouthed Car Salesman. Oblina and Krumm are mystified that whenever the word "human" is uttered, Ickis begins to act like the Car Salesman.

Krumm gets a bad case of the hiccups or in monster terms, ""the Nolox."" Every time he Noloxes, something terrible happens. It's up to Oblina and Ickis to find a cure for the dreaded Nolox.

Oblina, always the star pupil, finds herself challenged to the limit by a gifted transfer student from another dump.

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!

Through a series of misinterpretations, Krumm is convinced that Oblina has a crush on him. Krumm gets paranoid about what this will do to their friendship and tries desperately to avoid her.

Ickis, Krumm, and Oblina hit the human world on Halloween night with disastrous results.

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?

When a cocky Ickis takes a break from scaring to eat the grime of a dirty car, he inadvertently ends up in a car wash. Now covered with three coats of wax, the frictionless Ickis must slip and slide his way through an important scare. Luckily for him it's at an Ice skating rink! Ickis out "slips and slides" everyone.

TV's loveable Murray the Monster is undermining good ghouls everywhere, because kids aren't afraid of him.

The Monsters are foraging in the dump. Suddenly, bulldozers move in and begin pushing the garbage onto a huge barge where it heads off to sea with Oblina, Krumm and Ickis on board. At first it's party time, but soon, everyone wants to go home.

While above the ground, a puppy saves Ickis from being run over. He sneaks the puppy back to the academy and enlists his friends' help to hide it from the Gromble.

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.

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.
