Gran is the grandmother of the Crood family. She is also Ugga Crood's mother and supporting character in the Dreamworks animated movie The Croods. She is voiced by Cloris Leachman.
She is stubborn, and (like any mother-in-law) loves to tease/torture her son-in-law Grug, who eagerly awaits her death to come. But it seems like this old gal is sticking around for their long journey ahead of them. Gran may appear old, but she can be pretty handy with her cane if needed.
