Kids and there is a toddler on a zipline

The prehistoric Croods family live in a particularly dangerous moment in time. Patriarch Grug, his mate Ugga, teenage daughter Eep, son Thunk, and feisty Gran gather food by day and huddle together in a cave at night. When a more evolved caveman named Guy arrives on the scene, Grug is distrustful, but it soon becomes apparent that Guy is correct about the impending destruction of their world.

Searching for a safer habitat, the prehistoric Crood family discovers an idyllic, walled-in paradise that meets all of its needs. Unfortunately, they must also learn to live with the Bettermans -- a family that's a couple of steps above the Croods on the evolutionary ladder. As tensions between the new neighbors start to rise, a new threat soon propels both clans on an epic adventure that forces them to embrace their differences, draw strength from one another, and survive together.

Baby Bink couldn't ask for more: he has adoring (if somewhat sickly-sweet) parents, lives in a huge mansion, and he's just about to appear in the social pages of the paper. Unfortunately, not everyone in the world is as nice as Baby Bink's parents—especially the three enterprising kidnappers who pretend to be photographers from the newspaper. Successfully kidnapping Baby Bink, they have a harder time keeping hold of the rascal, who not only keeps one step ahead of them, but seems to be more than a little bit smarter than the three bumbling criminals.
