Waldo the Magnificent arrives in the store with a bad case of shrinkitis - whenever he sneezes, he shrinks. He needs a special potion to cure him that can only be gotten in ""potion land"". So while Muffy takes care of Waldo in the store, a magic genie sends Jeff, Jodie and Sam to potion land where they face a giant lizard, and go to a haunted castle. Everything scares Jodie and Sam but Jeff will not give up since he owes his life to Waldo. They eventually get the potion in the castle dungeon and make it back just in time.
