Waldo comes to the store in a bad mood, which isn't just an ordinary case of the blues. He has a case of the ""grumples"" which only magicians get. And if he lets the grumples have the best of him, he'll lose all his magic powers. He has remedies written on cards that the others search the store to find certain things like a stuffed bear, a rubber chicken, a string puppet, and a robot and must dance the ""Go-away-grumples Gavotte"" before Waldo is better.
