Totten is a recurring character in the Super Mario series, especially known from New Super Mario Bros. U and related titles. He is a shy, masked purple rabbit-like thief who steals items from the player, then runs away when approached.

In the series, he serves as a collectible or bonus-related character and adds a playful challenge to gameplay through his quick movement and evasive behavior.
