What could possibly go wrong when Jean, Petey, Kriss, Mom and Dad take a vacation in the country? Would you believe they wind up on a fearsome farm where all the animals have mutated into horrible monsters? Watch and scream (and laugh!) as colossal cows, outrageously over-sized chickens, pigs of preposterous proportions, dangerously deadly ducks, frightening fish, and a tremendous, terrifying turkey turn a fun family vacation into a never-ending nightmare!...

Petey and Jean love to draw monsters. They create Oko, a frightening monster who escapes from the sheet of paper and disappears into their house. All they need to do now is create a nice monster that eats bad ones. So they draw a nice monster named Kriss with three legs, four arms and ten mouths to eat the bad monster. The plan works and they decide to keep Kriss as the family's new pet monster. For Christmas, Jean & Peter go on vacation to the mountains...

Ham Helsing and his crew are back to fight more monsters at mysterious Camp Fish Head Lake.
