The Croods (2013)

An eccentric cave family named the Croods – consisting of Grug, Eep, Ugga, Thunk, Sandy, and Gran – survive several natural disasters by sheltering inside a cave for days and nights. The harsh circumstances influence Grug’s stubbornness, overprotective parenting, and refusal to let anyone leave the cave except for short periods of time to gather food, due to watching several of their neighbors die to natural selection. Eep loves her family, but frequently rebels against these structures, instead desiring to discover something “new” (a concept the family fears). One night, Eep sneaks out when she sees a light, and encounters an inventive modern human boy named Guy and his pet sloth Belt, who have made a torch. He warns her of an inevitable apocalypse that’s about to destroy the world and offers to help her escape, but Eep elects to stay with the family. Guy leaves her a shell horn to blow if she needs help, but when Eep returns to her frantic family, they destroy the horn out of fear of “new”.

A massive earthquake destroys the cave and the surrounding lands, and the Croods flee into a jungle they discover below their home mountains. Encountering a “Macawnivore”, a brightly colored feline whom Gran dubs “Chunky”, the family flees him, until he is scared off by swarms of “piranhakeets” that devour a ground whale. Making another horn, Eep calls to Guy, who rescues them with his fire. After a great deal of confusion regarding the Croods’ first contact with fire, Grug, begrudgingly realizing he and his family need Guy’s inventions to survive, imprisons Guy in a log so he can guide them to a safe place. To appease Grug, Guy suggests the Croods go to the mountain where there are caves, though in reality he and the other Croods doubt the wisdom of this.
