Ickis, Krumm, and Oblina are saddled with babysitting the Gromble's nephew, Bomble. They take him along on a garbage hunting trip to a local hospital where the baby monster is accidentally switched with a new-born human baby. The trio must track down the Bomble at the home of his new human ""parents"" and replace him with the human.

Ickis, Krumm, and Oblina discover an old movie in the dump, which they watch constantly despite the Gromble's protests. They begin to ape the characters in the movie and even try some dangerous cowboy movie stunts in their scaring.

Ickis accidentally eats a chocolate Easter bunny. The human food gives him a bad case of sleepscaring - the monster equivalent of sleepwalking. Terrified of his middle of the night scares, he turns to his friends for help.
