Alone in the dump, Ickis dons a cape and pretends to be his favourite comic book hero, "Ultra-Monster". Suddenly, he is accidentally thrown through the air by a bulldozer and inadvertently saves a group of students. It's a bird, it's a plane...it's Ultra Monster! Word gets around the academy that "Ultra-Monster" is real and very cool. When Krumm volunteers to play sidekick, "Stink Boy", a new dynamic duo is born. A substitute teacher arrives, announcing that The Gromble has "gone away" and that he will be taking over. The substitute lets the students do whatever they want - even garbage fights are allowed!
