When a group of "cool" girl-monsters shuns the obsessively rule-bound Oblina, she transforms herself into Oblina The Rebel--breaking every rule she can.

When Krumm is forced to wear glasses to correct his inexplicably blurry vision, he finds himself the object of mocking on the part of the other students. Krumm tries to go without his glasses, but he and all the students learn their value when a bespectacled Krumm saves a group of monsters after a scare goes wrong.

The Gromble is sick and Simpah, the horrible Cafeteria Monster, has been put in charge of the students. When she threatens to make them eat human food, Ickis, Krumm and Oblina beg The Gromble to come back. The Gromble says the only thing that will cure him is Gromble Soup, but you need special ingredients....the crown of a king, the head of a dragon and the tail of an ogre. Ickis, Krumm and Oblina each set out to obtain one of the ingredients.
