When Angela is asked to babysit, the monsters ask Nick how babies are made. As usual, they get the wrong end of the stick and Haggis ends up thinking he's pregnant. But will Eddie and Angela persuade him that the baby's not his before the real mother comes back?

When Eddie announces that he wants to become a full-time monster, his parents start to worry and encourage him to play with a normal boy. But when Eddie abandons the monsters to play computer games with his new friend, Fiend, Haggis and Norman create so much havoc that Nick finally snaps and dumps them in a forest.
