When Gran moves in with the family, she embarrasses Eep in front of the cool kids and drives Grug up a wall.

Eep finds her competitive nature taking over when she teams with her new friend to compete in the first-ever school hunting exam.

Eep and Thunk compete in a dare-off; Grug picks a fight with the moon.

Snooty neighbors move in next door and complain about the bone pile blocking their view, which launches the Croods into a prank war.

Everyone in the valley loves Thunk's first-ever movie, featuring shadow-puppet actors -- until they see the ending.

Eep takes advantage of a lack of adult supervision by throwing an out-of-control house party that nearly destroys the cave.
