Grug Crood 瓜哥

Gustey Crood is the main character and well-meaning, overprotective but outdated patriarch of the Croods family. Gustey keeps his family in line and believes strongly that things should really never change since they lost their neighbors from not being careful. As Eep says "Our family has lived their whole life living by my dad's one rule; never leave the cave". It is likely he got this from his father and possibly Gran because when the earthquake happens it is confirmed that Grug is forced to break tradition to save Guy, Eep, Sandy, and Ugga.
