The Fantastic Flatulent Fart Brothers Save the World!

Two gassy brothers.
One mad clown with Weapons of Mass Flatulation.
Can kid fart power save the world's butt?
Willy and Peter just want to sit around watching TV and farting. So it's pretty annoying when they're out shopping for their sister's birthday, and end up captured by mad clowns who want to take over the world.
From their bouncy castle dungeon to the White House itself, can Willy and Peter outsmart-and out-fart-the evil clowns? Can they save humanity from ex-stink-tion? And still get home in time for their sister's birthday?
"Two thumbs up and a belch!"

They're the smelliest new heroes on the block, in their own butt-blasting adventure series for kids ages 8 to 12. Even the most reluctant readers will laugh their underpants off!
