"Brabby & Nabby" are Gran's pet TripGerbils in The Croods. TripGerbils are 2 gerbils with 1 tail. They were first seen during the egg run in the beginning, then somewhere when the Turkeyfish was about to eat them, and near the end, they and a few other "pets" including Chunky join Grug's exodus to reunite with the Croods.
