Tails Doll

The Tails Doll (mistakenly called Puppet Tails) is a doll version of Miles "Tails" Prower built by Dr. Robotnik. He is comparable to Tails in the same way that Metal Sonic is comparable to Sonic the Hedgehog and Metal Knuckles is comparable to Knuckles the Echidna.

Tails Doll was created at Robotnik's Reactive Factory along with Metal Knuckles, and has a metal rod coming out of the top of its head leading to a red gem that seems to control Tails Doll's movement.
