I'm Stuck!

A bonus story as part of a 3-part mini series that ran in the "Adventures of Rosa and Mushmouth" collection. Mushmouth is a dim-witted Deinognathus (Metazoic carnivore) who is so big. He is too big to fit through an average doorway like what his friend Rosa has. But somehow Uncle Martin talks him into it. Mushmouth begins to feel sorry that he even listened to Martin when he gets his front half stuck in the doorway, while his bottom-half stays outside. No matter how much Martin tries to help Mushmouth, they still cannot get him free! Find out what happens. Will Mushmouth be able to get out of the doorway? Or will he be stuck in there for the rest of his life?
