An Obake Block (おばけブロック, Obake Burokku) is a very rare, possessed ? Block that appears in New Super Mario Bros. Wii. Only four of them appear in the secret area in World 7-. 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 an Obake Stand), breaking apart and releasing a coin if they hit the floor or a platform.
