On the Shrek Superslam Cheats, it says there's a way to unlock Fairy Godmother. To unlock her this is what it says.

1. Unlock all characters.
2. Complete all mega challenge events.
3. Complete Story Mode.
4. Do Melee on multiplayer Mode.
5. Do King of the hill on multiplayer Mode.
6. Do 1 Melee with each character.
7. Do 50 Melees with the same character each time.
8. Do 100 Melees with the same character each time.
9. Carry on doing Melee with one character only until you get 999 on each medal.
10. In the trophy room, there's a place where you can keep flying up until you reach an invisible roof. It says to keep on jumping back and forth on the top for 1 min and 30 secs. When you're done, you unlock Fairy Godmother.

Is this true? And do you have to do them in the order written?

I love Luna! She's my 2nd favorite character! My #1 favorite character is Anthrax. Oh well, I don't care anymore about Fairy Godmother.
