Grandmother Mole is one of the oldest moles in Never Land, the other being her significant other, Grandfather Mole. They have no children together, but consider all the moles to be family.[1]
In the books[]
She appears at the beginning of Beck and the Great Berry Battle, when Beck stops to chat with her. During the Berry Battle, she and the other moles had sided with the hummingbirds. Because the chipmunks had dug through their tunnels, they of course did not want to side but had no choice. At the end they all realize how silly they have been and make up.
