疯狂原始人：家谱
Struggling to find their purpose on the Betterman farm, the Croods see an opportunity to prove their worth by harvesting Phil’s perilous (and sticky) bounceberries.
When Eep wants alone time with her new friend Dawn, Guy seeks a new friend of his own and finds an unlikely companion in Thunk.
When the Bettermans invite the Croods to join their family game night, two things become clear: Phil needs to win and Grug hates to lose.
After a crowverine gliding mishap, Dawn loses her confidence and tells Eep she's taking a break from adventures. Eep convinces Dawn to join her on one last adventure – climbing Grrr Mountain.
When Hope oversteps by trying to teach Sandy manners, Ugga gets her revenge by challenging Hope to do the impossible: civilize Thunk.
Ugga has a secret - she's taking Eep to "flop with the bulrusses" - a fun and dangerous pastime Ugga enjoyed as a teen. Ugga's excitement fades when Hope invites herself and Dawn along.
