Chemical Plant Zone's bosses introduce more dynamic arenas and unique attack patterns.

- Act 1: Chemical Plant Mini-Boss (Crab Robot): This robot shoots bubbles. Wait for it to stop firing and lower its shield, then jump on its head. Repeat 8 times. Be mindful of the rising and falling chemical levels.
- Act 2: Dr. Eggman Robotnik's Mean Bean Machine: This is a Puyo Puyo-style puzzle battle. Match four or more beans of the same color to clear them and send garbage to Eggman's board. The goal is to fill his board completely. Focus on creating chains for larger attacks.
The Mean Bean Machine requires a different kind of skill, testing your puzzle-solving abilities.
