Propeller Box Artwork - Super Mario 3D World

The Propeller Block was first introduced in New Super Mario Bros. Wii, however, instead of the Propeller Box, it was called the "Propeller Block". It is a block, which Mario can wear over his body.

The Propeller Box is lost once the player finishes the level but rewards the player with an extra life. While wearing a Propeller Box, Mario can't throw boomerangs or fireballs, or turn into a statue, but they're still able to swing their tails.
