Amazing Island Cheats

This code is actually very funny. Once the shop is open near the
intermediate courses (across the greenish boardwalk) walk into the shop,
and their should be a little pig walking around. Go up to the pig and
press the A button. The pig will say " Oink?" Reply yes and you will
here a magical sound. Now whenever you are playing the minigames, there
will be pigs involved somehow. (If you ever want to turn this code off,
than go back to the pig and reply "no".)

After catching the Magma Ball, start spinning as fast as you can get without hitting the edge. Try to pause game play while the spin meter is in green. After that, resume the game and immediately press A. This should result in a red hit most of the time.

Some time in the game a pig will show up in the dock shop. Talk to it, and when it says Oink, select Yes. A noise will be played and now pigs will appear some way in all of the minigames.
