Ghost Block

A Ghost Block is a very rare, possessed ? Block that appears in New Super Mario Bros. Wii. Only four of them appear in the secret area in. They guard a Star Coin. They resemble a normal ? Block, but as the player approaches, they turn purple as they float over the character and throw themselves at the player (a very similar mechanism is used by a Ghost Vase), breaking apart and releasing a coin if they hit the floor or a platform. They can be distinguished from real ? Blocks by looking at the question mark; unlike the real ? Blocks, the question mark does not move, similar to the ? Blocks in Super Mario Bros.

Ghost Blocks also appear in New Super Mario Bros. U in Haunted Shipwreck and Spinning Spirit House, and in New Super Luigi U in Vanishing Ghost House. These roles are reprised in New Super Mario Bros. U Deluxe.

Conceptually, Ghost Blocks are much like Fake Blocks, while their method of attack is also very similar to that of the Invisighoul of Yoshi's Island DS throwing furniture - remaining still until approached, then swaying in the air and thrown directly at the player. A laughing Boo also implies it was thrown by one, as the furniture was by Invisighouls.
