Super paper mario! Probably one of the best games on wii.

Super paper mario isn't your average mario, or Paper mario. It was made in 2007, so it's pretty old.
The whole story is about a man named Count Bleck who has taken the Dark Prognosticus and plans to wipe out the world with it and make a new perfect world. At the very beginning, he forces Princess Peach and Bowser to get married, which summons the 8th Pure Heart. Throughout the worlds, Mario plans to find the other 7 Pure hearts to unlock each level and defeat Count Bleck. On your journey, a magical Wizard grants you powers to switch to a 3 Dimensional world!

As you go along, different farries, or Pixls, help you on the way. With the help of Bowser, Princess Peach, and Luigi, they all have to help together to fight Count Bleck.
TippiTippi is the main pixl, she tells you how/where/what you need to do for the next Pure Heart.
ThoreauThoreau lets you pick up things, such as enemies and throw them.
BoomerBoomer is basically a bomb, he can explode cracked walls and hurt enemies.
SlimSlim makes you disappear to the 2 Dimensional world. Enemies cannot see you, but as you move, they can.
ThudleyThudley lets you hit the ground with a tremendous force, he can also do bigger damage to enemies
CarrieCarrie can place a hover board below you which allows you to safely walk over spiky barriers, also good for stomping on the spiky enemies.

CudgeCudge basically gives you a hammer to whack enemies or destroy objects to see what lays behind them.
DottieDottie turns you into a small spec, you can go through small openings in walls or sneak up on enemies because they can't see you!
Barrie (Optional)
Barrie is a pixl you unlock after going back to World 4-1. He makes a spiky barrier around your player for a split second so you can ram into enemies, also great for jumping on spiky enemies or bouncing off projectiles!
Dashel (Optional)
Dashel makes you run really fast, she is found after beating "The Flopside Pit of 100 Trials."
Piccolo (Optional)
Piccolo plays fantastic music and changes your jump sound to the classic mario game. She also cures spells casted upon you.

Tiptron (Optional)
Tiptron is a Tippi replica robot you can buy from Francis in world 4-4 after beating him. It cost 999 coins which you don't really need it until you beat the game. It does basically everything else Tippi does.

Hope you have fun playing!
