Raccoons!

[Lady Birb]

Like, a random ghost is chosen at a random time to become the raccoon. The player can scurry through pipes and climb through all the disposal chutes. The player will earn points for being in a chute directly, where, upon close examination, has a 10% chance to say that the raccoon is inside! The player also gets BONUS points for sticking out of the chute, and grabbing whatever trash it can and eating it. Once the raccoon reaches X points, the raccoon wins and the end of the round announcements will say that the player won. Then the player is evicted from the raccoon and another ghost is selected to play it and the entire thing restarts!

This is one of the best ideas I have seen regarding giving ghosts something to do.
