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

When the city mayor declares a ""Dump the Dump"" recycling effort, the lack of garbage cans causes a crisis at the Academy, as the monsters run out of food.

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.

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.
