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.
