Timber is an adult female North American beaver. Named by Martin Kratt, she made her first appearance in the season 1 episode "Build It Beaver."
Background[]
She and her family are first seen when Chris and Martin took a crash landing on their dam and then a look inside. During the midst of the beavers building it, Sticker took Chris's paddle and when he tried to take it back the dam fell apart. So Sticker and Timber had to show Martin and Chris how to use beaver power to repair it.
