  9. 9

  10. 10
    Enter the corkscrew from the left to avoid falling into the abyss after the Boost Ramp post-Switch 1.

  13. 13
    Difficulty: Medium
  14. 14

    • When arms are near the ground, use appearing robots for Homing Attack to reach the boss's top.
  15. 15

  16. 16
    Later phases may have fewer arms and require dodging missiles while waiting for the top platform to appear.

  18. 18
    After the enemy hit bar is zero, run away from the ship to avoid crashing.

    Red Gem primarily helps avoid missile attacks.
  25. 25
    Yellow Gem grabs Rings and offers some protection.
  26. 26
    Purple Gem can reach the top but is slow.
  27. 27

    At one point, jump off a rail to catch a bud, then multiple buds, and Homing Attack enemies between buds over a bottomless pit.
  38. 38
    If a turtle goes into the water, use Aura and wait for it to resurface; it acts as a temporary platform.
