Whoopie Cushion

The Whoopie Cushion is an extremely rare item found by killing Giant Worms and Diggers. It makes a farting sound when used, and serves no other purpose. Each Giant Worm or Digger segment has a 1 in 500 chance of dropping a Whoopie Cushion.

Trivia
When used with a Cloud in a Bottle or a Cloud in a Balloon it makes it funnier because it is like a fart. It is the weirdest item in the game because it is almost useless but it has such a low drop rate.
