Since the first day of class, Liam’s farts had become the stuff of legend. And not because of how bad they smelled—which they did (like a tuna fish sandwich left in the sun). They were legendary because of the amazing things Liam could do with nothing more than the air from his butt.

Liam controlled his farts the way sculptors sculpted clay. He could fart any pop song on demand. He could stink-bomb a target one mile away. He could fart in Morse code (which only Yuna could understand). Liam was a true fArtist.

To no one’s surprise, the purple lightning transformed his butt blasts into something even more amazing. Liam now had SUPER-ATOMIC FARTS.

He ate a can of beans and hit the soccer field to test his new powers. “Go ahead, pull my finger,” he said.

Only Teo was brave enough to do it—and only since his super-speed allowed him to pull Liam’s finger and run halfway across the city to safety before

PPBBBBBBTTTTKABOOM!

The blast left a humongous crater outside the school—and a flaming hole in Liam’s underwear.

The heroes of Classroom 13 saw him as a force that could be used for good. The villains of Classroom 13 now saw him as a weapon that could be used for evil. All Liam saw was his butt hanging out in the cold air.
