Adventures of Sonic the Hedgehog: 4x4

Sonic Christmas Blast

Robotnik disguises himself as Santa Claus in order to force him into retirement and con the children out of presents during Christmas. During a visit to Robotropolis, Sonic and Tails rescue the real Santa Claus, who presents Sonic with a speed run test due to a ring Sally Acorn gave him as a gift serving as a key.
