Canyonopolis

Canyonopolis is a location in the Sonic Underground animated series.

History
The Sonic Underground once stayed here for a short time. When Dr. Robotnik found out that they were staying in Canyonopolis, he instructed Sleet and Dingo to go after them, though not before giving the two bounty hunters some Sonic Tonic to help them.

During their stay in Canyonopolis, Sonic went traversing the city in order to see if there was any trouble going on, only to run into Dingo and Sleet. Sonic ran back and warned his siblings of Sleet and Dingo approaching, though the two showed up just as Sonic was finished warning Sonia and Manic. With their new found speed, the two bounty hunters took down Sonic, tying him down with a chain, though Manic and Sonia managed to get away. Sleet then transformed Dingo into an iron ball and the two took him to Robotnik.
