Coin Box

Question Boxes are items introduced in the Nintendo 3DS game Super Mario 3D Land.

Question Boxes have an identical appearance to a Question Block. Like the Propeller Box, they can be worn by Mario (or Luigi) over his body and stay with them until the end of the level. While inside a Question Box, infinite coins will pop out from it while Mario is walking, jumping or being launched from a cannon.

Mario can only use it when he hits it from below. If it is ground pounded or hit by Tanooki Mario's tail, it'll just make a popping sound effect.

Question Boxes are only found in World 8-1, World 8-3 and Special 1-3. If Mario is touched by an enemy while wearing a Question Box, he loses it. If he touches a Flagpole while wearing one, it will disappear and give Mario an Extra Life.

In New Super Mario Bros. 2, Mario or Luigi can wear similar Brick Blocks on their heads, and get many coins as they move. These items look normal Coin Brick Blocks at first, but will turn golden after taking all its coins.
