Layout
The player starts on the main beach planet with Crabbers and a cannon. In order to open the gate to the left and continue, the player has to use the cannon to reach a small brown planet with many Octoguys and a Fire Flower. Grabbing the Fire Flower, the player must use a Sling Star to quickly return to the main planet and light both torches next to the gate, which will open it, before the Fire Flower power-up wears off. The gate will lead the player to an area filled with water. Diving underwater, the player will find a group of Star Bits aligned in the shape of an arrow, at the end of which is a Lever Switch that will lower a gate in front of it when activated. Moving up, the player will find another gate; activating the switch near it will open the gate, allowing the player to surface at a ghost ship. By climbing onto the deck of the ghost ship, Kamella will appear and challenge the player to a fight.

Kamella will attack by sending out either red or green magic bursts. The red magic will turn into a fireball upon landing on the ship and the green magic will turn into a Green Shell. Grabbing the Green Shell and throwing it back at Kamella will damage her and she will begin moving around the ship. Damaging her a second time will cause her to move up to the crow's nest above, and she will call up two Magikoopas to aid her. Throwing two more Green Shells at her will defeat her, rewarding the player with the Power Star.
