Other mistake: In The Croods, Guy was handing out bananas and gave one to Grug, which he threw away. But in this film, he does everything to get this mystical fruit that he hasn't had since his childhood.
Continuity mistake: When Guy's face is painted yellow, his hair is also covered in paint. A shot later his hair is spotless.
Continuity mistake: During the punch-monkey fight, Phil Betterman lies on the floor, exhausted, with his pendant resting on the floor, next to his ribcage. In the next shot it lies by his chest. Though he could have moved it between shots, the movie implies he is so tired he is lying motionless on the floor all the time.
