|Family||Grug (Father), Ugga (Mother), Thunk (Brother), Eep (Sister), Gran (Grandmother)|
Sandy is the youngest in the family. She is known to be "rough" like Eep, she has red hair and peach skin the two share a resemblance. Sandy is unable to talk and instead bites and growls although her first words turn out to be "Dada"(as in a childs word for dad) and "Whee!". Sandy isn't known for her cuteness, but her constant bitting of family members and creatures. The family used her as a weapon during a hunting trip once. She is comforted by Krispy Bear formally Eep's.
The youngest of the Croods, four-year-old Sandy is as feral and vicious as a baby wildcat. In a dangerous world full of creatures trying to take a bite out of her, Sandy is not afraid to bite back.
Sandy has big dark brown eyes, and two buck teeth. She wears a paw as clothing, and has two pigtails secured with millipedes. Her nose is also quite large.
