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 normal ? Blocks, 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 marks; unlike on the real ? Blocks, the question marks do not move, similar to those of Blockhoppers from New 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 being thrown directly at the player. A laughing Boo also implies it was thrown by one, as the furniture was by Invisighouls.
