In a post-apocalyptic world, AV (Anti-Violence) Club members Tip, Mindy, Owen, and Xen develop semi-super powers and use them to try to save their middle school.

Principal Smelt has created the Fun-ger Games for Softrock Middle School's students, and Rob Burnside, his life in ruins, hopes that Katfish, a cross between Katniss and the Little Mermaid created in Rob's closet, will help with game tips, advice about girls, and how to get people to stop hating him.

Twelve-year-old Rob has stuffed his closet with old laboratory experiments, unread books, and more, and when a creature emerges from that chaos causing a great deal of trouble, Rob has to do such horrible things as visit a library and speak at a school assembly to set things right again.
