Phases & Attacks:

  1. Bubble Drop: Robotnik drops large chemical bubbles that bounce around the arena. These are dangerous to touch.
  2. Chemical Pool: The chemical pool in the arena will periodically rise, forcing you onto higher platforms.

Strategy:

  • Dodge Bubbles: Avoid the bouncing chemical bubbles. They can be destroyed with a Spin Attack, but it's often safer to dodge.
  • Hit Robotnik: Robotnik is vulnerable at all times. Jump and hit his Egg Mobile when he is within reach.
  • Manage Chemical Pool: When the chemical pool rises, quickly move to the higher platforms. Use the Spin Dash to gain height if needed.

This boss requires 8 hits. The main challenge is managing the rising chemical and dodging the bubbles. Stay on the higher platforms as much as possible to avoid the chemical.
