Blockhoppers are enemies that are made up of a ? Block and 2, 3, 4 or in some cases, 5 Brick Blocks.
- They can be distinguished because the ? doesn't move, unlock a regular ? Block.
- They cannot be jumped on, but they can be attacked with a Ground Pound.
- Standard Mario can damage these, even though he isn't able to Ground Pound.
- When the ? Block is smashed, the player will get a prize of a Coin, Super Mushroom, or Fire Flower.
