Blockhoppers are enemies encountered in the game New Super Mario Bros.. They are found only on World 2-5. They disguise themselves as a ? Block with Brick Blocks on top of them, which can be distinguished by the fact that the question mark on them is motionless. Once Mario or Luigi approach, they reveal a black body with blue feet. They hop in cue with the background music, and if standing on top of it, the Blockhopper will move in the direction that the player is facing. They can be defeated with either a thrown Koopa shell, a Ground Pound, or by running into them using the shell dash ability using the Blue Shell. If the ? Block on the Blockhopper is Ground Pounded, the player will receive a coin or an item like an ordinary ? Block.
They are similar to the Pile Driver Micro-Goombas that disguise themselves as blocks from Super Mario Bros. 3. Blockhoppers are also similar to Blokkabloks, considering that both enemies are made of blocks.
