A sudden mudslide buries a family's backyard ... and their beloved dog, too! Did he make it inside his doghouse before the slide hit? Even if he did, the doghouse was pushed off its foundation and there's no telling where it is now. Watch as the Critter Gitters, with the help of Rocky the Chimpanzee and Rex the Rescue Dog, attempt to locate the doghouse under tons of mud and rescue the dog before the rest of the hill slides down.
