Did you ever wonder what that weird looking bird is doing? Press B to hear a combination of sounds (fart, burp, hiccup, and bacaw). Press Start followed by C-Up, C-Down, C-Left, or C-Right to hear the same sounds. Try to match the series of sounds given by the bird to learn new codes. The name of the code will be displayed if entered correctly. This may be done every time a ball (crystal) is returned to the castle. Complete the game or enable the "Open Portals" code to receive new codes rapidly.
