? Block

The '''? Block''' is one of the many blocks found in the Mario universe.

? Blocks are commonly seen floating in midair, often containing Gold Coins, Super Mushrooms or Fire Flowers.

In the Paper Mario Series, Red ? Blocks contain badges and yellow ones contain coins or items.

? blocks are sometimes invisible at first. They are turned visible by jumping into them (or using Watt in Paper Mario). Once they're visible, they can be used as stepping stones.

In Super Mario 64 DS, red ? blocks replace the red, blue, and green ! blocks. They contain either Power Flowers or Bob-ombs, depending on character and hat status.

In the Mario Kart series, similar item blocks, called "Item Boxes" are found on every track, each containing an item to be used to assist you in the race.
