Phil enlists the Croods to help him retrieve a rare fruit before some wild animals can. But when Grug doesn't trust Phil's methods of getting it back to the farm, the Croods and Bettermans compete with each other more than with they did with the animals.

After a big argument between the Croods and Bettermans, the parents decide to separate the two families. Not wanting to split up, the kids try to convince the parents to make up before the Croods move off the farm entirely.
