Programmer looking for help on a Wario Kart game

[Cdiplayer]

Oh, how about some enemies and bosses from the wario land games as unlockable characters?

Here are my suggestions:
Hammer-bot
Donutteer
Appleby
Pirate Goom
Shoot
Zenisuki
Hinyari
Zombie

Good suggestions. At some point I will also probably hold a poll on who should represent Wario's Woods as a playable character in the game. I may end up just putting Toad in the game.
