Tails Doll

The Tails Doll (テイルス・ドール) (also mistakenly called Puppet Tails or Tails Puppet) is a robot/doll version of Tails built by Dr. Robotnik. He is comparable to Tails in the same way that Metal Sonic is comparable to Sonic. The Tails Doll has a metal rod protruding out of the top of its head that leads to a red gem that seems to control the robot's movements. The Tails Doll appeared only in Sonic R, as an unlockable character on the Radical City course by collecting 5 Sonic Tokens, finishing in at least third, then beating him in a race. He is known to be the slowest character in the game, but he can float over water like most of his metal allies, and he can also fly much longer than Tails can.

Profile
Sonic Channel provided at one time Sonic R's profile descriptions for each of the characters. The following is the information provided for Tails Doll:

''As a last resort, Eggman manufactured this to catch Sonic unprepared. This, except for the power plant embedded in its head, is a mere stuffed animal, whose meager form nevertheless exhibits considerable ability in races due to its lightweight design. Still, it is also able to float in the air for a long time.''

Trivia
