Instructions
When you encounter a pirate, stand still and aim the Wii remote at his chest.
Hit the pirate with a blast of thinner by pressing and holding the "Z" button. Thin out his outer casing completely.
Wait for the pirate to get angry and spin around. This will take a few seconds. Do not approach the pirate while he is attacking.
Once the pirate stops spinning, a green button shaped like a gemstone will appear on his back. Run up to the pirate and shake the Wii remote to launch Mickey into his spin attack to defeat the pirate.
