That game would be the only one to star an environmentally friendly marsupial, Awesome Possum Kicks Dr. Machino's Butt. Awesome Possum is here to clean up the world. Don't worry - Awesome will tell you. You and Awesome take on the littering Dr. Machino and his chainsaw goons. Clean up rancid rubbish and fight putrid pollution and collect recyclables to win big points.
Some people think swimming in freezing water is fun, too.
Recyclables replace the rings, and you get an extra life and full health once you collect fifty of them. Like Sonic, there are checkpoints to save your place, and also like Sonic you must touch a sign to end each level, along with fighting a boss at the end of each world. You can also earn the chance to compete in a bonus level at the end of the round. There are a couple of things that makes Awesome Possum unique, though. After stomping on an enemy's head, you spin into a little ball and become invincible to everything except explosives and spikes.
