Unlock codes for effect codes: Purchase the Hard Drill when it becomes available at
the shop. It will allow you to access the secret MaiMai room in
the tutorial world. In the room is a four digit combination lock.
There are three unlock code levels that each unlock its passwords,
as well as the passwords of the previous level(s). First, choose
one of the digits and press Start while the drill is inserted
to reset the code to 0000. Then, set each of the digits of the
unlock code to their correct number in order. When the correct
unlock code is entered, the lock will automatically reset. You
can continue entering another unlock code, or enter one of the
effect codes for the level unlocked, or a lower level. If you
leave the room the unlock codes must be re-enterd.
Level 1: Set the third number to 1, first number to 2,
fourth number to 3, and second number to 4 in order
to display 2413.
Level 2: Set the third number to 8, first number to 6,
fourth number to 5, and second number to 3 in order
to display 6385.
Level 3: Set the second number to 8, fourth number to 2,
first number to 3, third number to 5 in order to
display 3852.
Effect codes: The following codes can only be enabled after the corresponding
level code (or higher level code) has been entered. There is no
required order for the digits to be entered. When a correct code
is entered, a chest with the bonus will appear from the purple
brick pipe in the secret room.
