Power-Ups

• Mushroom — Makes Mario twice his original size. 'Super Mario' can break brick blocks from above and below, and will return to regular Mario if hit.
• Fire Flower — Turns Mario into 'Fire Mario', enabling him to shoot up to two fireballs at a time. When the Wii Remote is shaken, Mario spins and throws one fireball in each direction. When hit, Fire Mario returns to Super Mario
• 

  One of the new power-ups in the game, the Ice Flower. 
  Ice Flower — Turns Mario into 'Ice Mario', enabling him to shoot up to two snowballs at a time. Snowballs will break after two bounces, and can freeze enemies, which break free after a short time. Mario can pick up most frozen enemies and either throw them into other enemies, in the manner of a Koopa Shell, which will break upon contact with a wall. Underwater, frozen enemies will float to the surface, and in the air, frozen enemies will remain in the air for a few moments (serving as a platform) before falling and breaking. When the Wii Remote is shaken, Mario spins and throws one snowball in each direction. When hit, Ice Mario returns to Super Mario.
• Propeller Mushroom — Turns Mario into 'Propeller Mario', which allows Mario to fly upwards, when the Wii Remote is shaken. Mario will float down to the ground after ascending, but can drill downwards by pressing down on the D-Pad. Mario must have touched land after using the power before he can use it a second time, and will return to Super Mario when hit.
• Penguin Suit — Turns Mario into 'Penguin Mario', which gives Mario several unique abilities. Penguin Mario can shoot snowballs, like Ice Mario, can walk with enhanced traction on ice, can slide on his belly when he gains a run-up, to crash through enemies and brick blocks, or to slide along water quickly, and can move through water much faster and much more controlled. When hit in this form, he'll return to Super Mario.
• Mini Mushroom — Turns Mario into 'Mini Mario'. Mini Mario is a quarter of the size of regular Mario, and can only take one hit before losing a life. Mini Mario is too light to cause damage to enemies by simply jumping on them, so to attack enemies, he must use a ground pound. Mini Mario is light enough to walk on water, and can enter tiny hidden passageways and pipes, to acquire certain star coins or access certain exits.
• 

  Star power! 
  Star — The Star turns any form of Mario invincible for a short while, allowing him to walk through any danger, eliminating 7 enemies in one touch for a grand total of 16,400 points and 1-Ups for 8 or more enemies!  When activated on the map, Mario can avoid encounters with enemies, and will remain in effect until he enters a level.
• Yoshi Egg  — The Yoshi Egg also summons Yoshi during their adventure. When summoned, Mario & co. can ride on that Yoshi and eat any enemy or item along the way. When the stage is completed, they drop off and can be summoned again in later levels.
