From the Super Mario Wiki
Timber is a tiger who makes his first appearance in Diddy Kong Racing. His parents left him in charge of their home island. Wizpig later invades the island, prompting Timber to call upon the help of his friends who take on Wizpig's challenge to race for the island. He's a middleweight racer who rides green vehicles with average speed, but his other stats are pretty low. Despite those drawbacks, he controls very similar to Diddy Kong, and is ideal for starter players.
Timber reappears in the Nintendo DS game Diddy Kong Racing DS. He seems to have an Australian-like accent in this game. His appearance has slightly changed in this game, with Timber having more, darker stripes, and the Nintendo DS logo on his cap instead of the Rare Ltd. logo that his cap had in the original game. All of his stats are average in this game, unlike with the original title. Timber's instrument theme is a harmonica.
- Due to Microsoft buying Rare, Timber's hat now has the Nintendo logo on it, similar to Diddy Kong. However, artwork in the Diddy Kong Racing DS manual depicts the Nintendo DS logo on his hat.
