Legend Of Zelda: Majora's Mask Cheats

If you go in the post office in clock town, you will see a counter where if you could, slip things through a little slot through the bottom of the glass wall. Z-target and back flip onto the counter and run into the glass with the opening. If you do it right somewhere around the middle, you will phase through it no problem.

MINI EASTER EGG: If you look in the Post Man's closet you can see a small silver bunnyhood picture on his hat and backpack.

After you get the Zora's mask, go to the place in clock town where there is a washing pool. Jump into the water and sink down. Now go over to the ledge that's under water and try to climb it. You can't. You skip half of the animation and "teleport" to the top.
