Tails Doll

The Tails Doll (also mistakenly called Puppet Tails) is a doll version of Miles "Tails" Prower built by Dr. Eggman. It is a secret character in the game Sonic R, unlocked by finding the 5 tokens in the Radical City track and finishing 1st, 2nd or 3rd in the race. Tails Doll has poor handling, average acceleration and average top speed. Its jumping abilities are quirky, too, since it cannot jump very high, but has a strange floating ability as its "air action". It is also the only character who can float over the water without slowing down after a period of time. Tails Doll is also one of the few characters who did not appear in the character poll by Sonic Channel, which featured multiple exceedingly obscure characters, such as Ray, Bean, and Bark. It can be guessed he was created by Dr. Eggman as a robotic counterpart to Tails, much like Metal Knuckles and Metal Sonic, but used a plush body because Tails' fur cannot be duplicated by metal.

In Sonic Adventure, there are doll versions of Tails, as well as Sonic and Knuckles. They are however just practice dummies for Eggman's robots, and are not "intelligent" like Tails Doll. These dummies got their own collectable cards in Sonic Rivals, with the Tails one being named "Tails Doll".
