The toilet vortex

"Something is rotten in the plumbing of Harry Buttz Elementary School, and it's kidnapped Janitor Stan! It's up to the Fart Squad to dive into the toilet vortex to save their scent-sei from the World of the Royal Flush ... Only the Fart Squad has the guts, the gall, and the gas to flush this round brown mound before he overflows his toilet kingdom on the world."--Provided by publisher.
