Plop!

Grandma Eunice's old house has a secret, and it's buried in her backyard. When Malcolm and Dandy uncover an old soda bottle from the 1939 World's Fair, they're sure there's something inside. But they didn't count on it being a bothersome ghost that likes to squirt them with glop. Can Malcolm and Dandy find a way send this soda jerk on its way?
