Kirby: Nightmare in Dream Land Cheats

Sword: Slash at your foes underwater
Hammer: Break blocks and send a giant hammer upon your foes
Parasol: "Pop" your foes when they hit the top of this umbrella

I would like to tell you about, well, a few cheats I found (hence the name.)
When our short, pink hero inhales two enemies, a randomized slot machine-like game with all the powers will apear where it shows your power.
Press A to stop the reel to give you your power! Here's the next one. Defeat Nightmare Industries in extra mode to unlock MetaKnightmare!!!
This is a special minigame that allows you to control MetaKnight playing story mode. By the way, no saving. One more thing, Metaknight's sword cuts through anything... even steel boxes.
Oh, and you only get half your vitality, just like extra mode!
Have fun!
This is AaronC.Heuer signing off!

Beat the game 100% to unlock extra mode. Beat extra mode 100% to unlock the mini-game "Meta Nightmare" which allows you to play the game as Meta Knight!! The downside: you can't save, so you have to beat it in one sitting.

To unlock Boss Mode, beat the game once.
