It's show-time for Leo! This evening in the school play he is to play the role of the wizard. For the time being, he is in his room rehearsing and it isn't going too well. Luckily Mot brings him back a role-model: a real wizard! Ralph Machinello! The best of the Middle Ages, or so they say ... With all the good will in the world, Ralph drones a series on incantations with unexpected and disastrous consequences. A booming Swiss cuckoo bursts forth from the neighbor's throat, Aunt Zelda becomes a horrifying virago, Mot is Leo, Leo is Mot, and Ralph is a bat who must be caught if ever one is to undo this surfeit of spells.
