Wienerville is a location that appears in the Adventures of Sonic the Hedgehog television series. It is the weenie capital of the planet Mobius that is famous for making the world's greatest sausage (and the best Chili Dogs on the planet). Appropriately all the Mobians who live in the city are walking talking sausages themselves. Mayor Knackwurst is the leader of the city and he encourages his people to support his hero, Sonic the Hedgehog.
When Sonic and Tails visited Wienerville for the first time, they were immediately welcomed by Mayor Knackwurst himself and were given a huge complimentary feast. However, Gizmo Gas blew in that was created by a machine that had been created by Professor Von Schlemmer and then stolen by Dr. Robotnik. After Tails inhaled the gas he become a giant and started destroying the city, unintentionally. Robotnik convinced the citizens that Sonic turned Tails giant on purpose and he gave them presents so they would join his side. The citizens chased Tails out of Wienerville and hunted him down.
With the help of Professor Von Schlemmer, Sonic was able to restore Tails back to normal and convince the citizens that Robotnik was lying the whole time. After that, Sonic and Tails were welcomed back to Wienerville and given a few hundred complimentary Chili Dogs.
