Max stole a gold statue of Doctor Robotnik from Sleet and Dingo. Sleet began to pursue him on a motorcycle, so the pickpocket asked the Sonic Underground for a ride. They refused at first, but they changed their minds when they noticed Sleet giving chase.
Later, Max hid behind a curtain and videotaped Sleet and Dingo talking about their plan to make off with taxes that they were supposed to give to Robotnik. He used the tape to help the Sonic Underground by proving Manic's innocence, even though he stole a coin from the Duke of Velcronia.
Max and his posse were given homes by the Duke of Velcomia afterwards, and Max joined the resistance.
