Tails Doll is a very minor character from the Sonic the Hedgehog franchise. Tails Doll has had only one in-game appearance, Sonic R, and a few appearances in other media, primarily comics.

It is little more than a patchwork plush toy bearing resemblance to Miles Prower, featuring no mechanical parts save for an implied power supply and the antenna protruding from it's head.

Most of Tails Doll's infamy comes from various creepypastas made about the character and it's inherently creepy appearance and lack of any in-game personality or backstory.
