Tocky

Tocky is a turtle that only appears in 16-bit version of Sonic the Hedgehog 2.

Description
Tocky has peach-colored skin and green shell which is orange from belly section. Being part of animal friends of Sonic the Hedgehog, Tocky along others gets kidnapped by Doctor Robotnik who uses him as power source for his badniks. Tocky is only featured in Sky Chase Zone and has not appeared since then.

Trivia

 * Tocky could possible be the inspiration for the character Tommy Turtle from the Sonic the Hedgehog Archie Comics.
 * Tocky has a walking animation (see above), which can't be seen in the game, since Sky Chase Zone doesn't have any kind of platform where travel (with the exception of Tornado's upper wing).
 * Near the end of Sonic the Hedgehog: The Movie there was a turtle (a failure version of Hyper Metal Sonic) that had the CD with Sonic's data on it which looks very similar to Tocky.
