Mumbly and Shnooker are assigned to guard people and their valuables at a mansion, where a magician named The Great Merlini is performing. Shnooker thinks that it is an easy job, but Mumbly is suspicious of Merlini. When Merlini uses a magic trick to steal Shnooker's badge, a necklace, and a watch, Mumbly goes after Merlini to arrest him. Merlini tries to escape using his magic wand, but Mumbly is always faster than he is.
