Uh-Oh! Cavity Sam's dog, Rex-Ray, has eaten a bunch of things he shouldn't have like homework, socks, bunny slippers, and a dog bone. Players try to help him feel better by removing them. Drop an ailment into the dog's mouth and use the magnetic Dog-o-scope to guide it along his belly -- hoping it'll come out his tail end. But watch out for the buzz! If the buzzer sounds the ailment drops. If it falls out of his belly, that player's turn is over.
