When Joe Gravo, a teenage suricata boy, comes to visit his uncle, a freaky inventor, he finds that his uncle’s laboratory is empty. A note left on the door says that his uncle went to stop evil Dr. Badbadman who has stolen his newest inventions and is planning to use them to conquer the world. It is unthinkable that Joe Gravo could stand aside when so much is at stake. Our young hero jumps on his gravoboard, his faithful companion in times of trouble and sets out on a rescue mission.

His heroic quest leads him through the green meadows, burning lava fields and the assembly halls of an old factory. In order to success, Joe will have to overcome many obstacles and learn how to use his gravoboard to its limits. Long jumps, loopings, furious speed, breaking through walls... nothing is impossible when you have courage – and a well-tuned gravoboard!
