Summary
Bunnie Rabbot has been kidnapped and is being held in an undisclosed location. Robotnik challenges Sonic to an extreme sports challenge, promising to release Bunnie if Sonic bests him in a wide variety of events. Even though Sonic knows it to be a lie, he accepts the challenge in order to distract Robotnik while the rest of the Freedom Fighters uncover the location of Bunnie and stage a rescue.
