The Used Block is a type of block that is found in the Mario series. It first appears in Super Mario Bros. and it is been said that Toads were turned into Question Blocks, Brick Blocks and several other blocks. These blocks only appear after Mario or Luigi have hit a Question Block or Brick Block that contains an item or coin(s). They are usually square and brown with rounded edges. In Super Mario World, they have small, closed angry eyes. When the player has hit a P-Switch, all Used Blocks turn into coins or vice versa for a small period of time. They can also be broken by Mario or Luigi when using the Mega Mushroom in New Super Mario Bros. and New Super Mario Bros. 2.
