Propeller Box

A Propeller Box is a power-up first seen in Super Mario 3D Land. It is an orange block with eyes, and a yellow propeller. The player is able to wear it over their bodies. The blades of the propeller can be used to rapidly fly into the air to a great height, and then slowly fall back down towards the ground. The Propeller Box is lost once the player finishes a level, but an extra life is rewarded. While wearing a Propeller Box, Mario or Luigi can't throw boomerangs or fireballs, or turn into a statue, but they're still able to swing their tails.

Propeller Boxes also appear in the follow-up title Super Mario 3D World, where they act in a way similar to the predecessor, though now the box color depends on which character is wearing it (e.g. green for Luigi).
