Propeller Mushroom

The Propeller Mushroom is a new item to the series introduced by New Super Mario Bros. Wii. As the name implies, the item is used to let the player fly through the air, spinning like a propeller until gently floating to the ground. Descent can be delayed if the player shakes the Wii Remote while going down. If no one reaches the item soon enough, the Propeller Mushroom will fly out of the stage. In order to activate the propeller, the player must shake the Wii Remote. Propeller flight is not continuous, but after the player lands he or she can fly again.

A player can grab onto another user who currently has the Propeller Mushroom. To do this move, the player must hold the one button and shake the Wii Remote. Then the player that is holding on to the other player can shake the Wii Remote again, making both of them fly. If the player shakes the Wii Remote when someone else is holding on, the player that was holding on will fall off, and if the player gets swallowed by a Yoshi, they can shake the Wii Remote and fly out of the Yoshi's mouth. The Propeller Mushrooms's appearance is an orange-capped Mushroom with two light-yellow spots and a yellow propeller atop the cap. Getting a Propeller Mushroom turns the player into their Propeller form, adding a jumpsuit (in color of the character) with a large helmet-like cap that has a propeller sticking out of it and the player's emblem emblazoned on its sides. It debuts in World 1-1.

It was originally a Propeller Suit, acting much like a P-Wing suit with a propeller. And a Propeller Block shares that same effect

Trivia

 * The idea of emblems on the sides of the suit was first used in Super Mario World cartoon in the episode Born to Ride.
