When the monsters are impressed by a few of Dad's old magic tricks, Fiend decides to become a master magician. Of course, he is useless, and manages to chain Angela and Norman together - just as Angela has a date coming over to watch a DVD!

When Eddie tells the monsters about swapping teeny pets - free toys that come in cereal packets - Fiend becomes addicted, determined to build the biggest collection of teeny pets ever. Meanwhile, it gives Kate and Nick the idea to swap roles - leading to even more chaos in the household.

When the monsters are left home alone while the family visit Kate's parents, they receive a surprise visit from a couple of burglars. The burglars certainly get more than they bargained for as the monsters defend the Carlson house in true monster style.
