A Brick Block, sometimes known as a Brick, is a block that has made an appearance in nearly every Mario platformer to date. As its name implies, Brick Blocks are blocks made of bricks. Their first appearance is in Super Mario Bros..
In all Mario platformer games, Mario or Luigi can only break this block as Super Mario (or Super Luigi) or another form of Super Mario, such as Fire Mario. By jumping into it from beneath (or ground pounding in some games), the Brick Block shatters, giving the player ten points (fifty in Super Mario Bros.). If Small Mario hits the block, it just bounces up slightly. Either way, an enemy walking on the brick will be injured.
