Eggman arrived in Las Vegas with his henchmen in order to demand money from the inhabitants there. At the same time, Sonic and his friends had also showed up at the Thorndyke Crest Casino in celebration of said location's grand opening. Although Sonic stuck around for a while, playing Speed Team Racing with Chris, he quickly got bored and left, eventually ending up in Wisconsin.

While the hedgehog was absent, Eggman made his move, demanding the people hand over all the casino chips and threatening them with a slot-machine robot. While Amy and Tails attempted to stop the robot, it wasn't until Sonic returned and joined them that they succeeded in taking it down.
