The Sonic Underground once stayed in Canyonopolis for a short time. When Dr. Robotnik found out this, he instructed Sleet and Dingo to go after them, though not before giving the two bounty hunters some Sonic Tonic to help them.[1]

During their stay in Canyonopolis, Sonic traversed the city to see if there was any trouble going on, only to run into Dingo and Sleet. Sonic ran back to warned his siblings, though the villains showed up just as Sonic was finished warning Sonia and Manic. With their new-found speed, the two bounty hunters incapacitated Sonic, though Manic and Sonia managed to get away. Sleet then transformed Dingo into an iron ball and the two took Sonic to Robotnik.[1]
