Tranquil Gulch is a location that appears in the Adventures of Sonic the Hedgehog television series. It is a small western town that often comes under attack by Robotnik because he wants to turn it into a casino-like town called Gambler's Gulch. Its people are very stern in not letting things happen and also trust their sheriff.
Tranquil Gulch's mayor is Mayor Chestnut, who appointed Sonic as the local Sheriff to get rid of Robotnik after the previous Sheriff (a rabbit) was scared away by Six Gun Pete. Once Robotnik was defeated, Sonic retired and was appointed the local bartender, leaving Miss Possum as the new Sheriff.
