The Croods Family Tree

When Grug overhears Thunk accidentally call Phil "Dad" he tries to reconnect with Thunk by taking him to the natural spectacle known as "Big Shine."

When Phil invents a simple new game called ball-in-cup, everyone except Hope, can't stop playing it.

When Grug thinks his forehead looks too big in Ugga's family portrait, she strives to make the painting disappear.

When the adults exclude the kids from their adult-only cave, the kids make their own much cooler cave, soon making the adults want to switch caves.

When a freak lightning strike turns Thunk into a genius, Phil is thrilled to have someone likeminded on the farm.

Tired of the farm's feud with the neighboring punch monkeys, Ugga arranges a punch summit.

When Phil detects a meteor is hurtling towards the farm, the Bettermans and Croods must decide how to spend their last day on earth.
