Once again, Mario's eternal quest to impress the princess yields a fabulous game. It's the usual run-and-jump rules of Mario ... collecting star pieces (instead of coins), stomping on things, shooting stuff, and beating up bad guys.
You start out running around on teeny planets, like the little prince but with less French. Then there's a part where you get a pair of bee's wings. Another part and you're flipping tiles by walking over them, trying to make 'em all match. After that you might ride a manta ray down a water slide. The same wacky stuff you'd expect from a hero who collects mushrooms.
When this disc isn't *in* the Wii, it's right next to it!
