You know, I just found something really fun to do...
Kill everything with light arrows in WW. It works on EVERYTHING!!! It can speed up the time if you have a contest on who can get through the savage labyrinth the fastest (another good kick, I can do it in less than 40 minutes).
Also, in majora's mask, after doing the feirce diety glitch (in earlier post by me), go to the town and walk into the maze game area. Its kinda funny how they treat you as a kid. Then I walk out and see how long he will keep his legs under the ground (just a glitch, he's too tall tofit through doors) then I talk to a bomber and get the game frozen, so I have a pretty grand time.
Oh, in WW, experiment with every creature possible how to kill them. Like you can flatten a wizzrobe in one hit with the hammer, blowing up stalfos with bombs, and throwing almost exploded bombs into floormasters' hands.
