Cheat Codes:

Successfully complete the "Treasure Trove Cove" world, then return to Banjo's
house. Go up to the picture of Bottles the mole hanging above the fireplace and 
press C-Up to look at it. Make sure you are standing on the carpet. Press R to 
play a bonus mini-game with a moving puzzle. There are seven puzzles in all. 
Complete each puzzle to receive a new code. Then, return to Treasure Trove Cove 
and enter the sand castle that you previously drained the water from and spell 
out one of the following codes on the floor of the sand castle with the Beak 
Buster move. Note: Using two or more codes that do not reveal eggs or the Ice 
Key will delete your saved game. These codes are not saved and must be 
re-entered with each new game session.
