Finish the stories
Clear Hero and Dark to reveal the Last story, then return to stages and extra modes for more emblems.
Mission ranks
Most action stages have five missions with different goals. A-rank requirements vary by stage and mission, so a fast time alone is not always enough.
Chao competitions
Raise Chao for racing and Battle’s Chao Karate. Fruit, animals and Chaos Drives all contribute to your garden progress.
Green Hill
Collect all 180 emblems to unlock the bonus Green Hill stage. Plan for story missions, high ranks, extra modes and Chao challenges.
