Editing Ghost Block

A '''Ghost Block'''<ref>{{cite|publisher=Dark Horse Books|title=''Super Mario Bros. Encyclopedia: The Official Guide to the First 30 Years''|page=150 and 215|date=October 23, 2018|language=en|isbn=978-1-50670-897-3}}</ref> is an obstacle introduced in ''[[New Super Mario Bros. Wii]]''. Only four of these possessed [[? Block]] appear in the secret area in {{world-link|7|ghost|World 7-Ghost House (New Super Mario Bros. Wii)}}, guarding a [[Star Coin]]. They resemble normal ? Blocks at first, but they turn purple when approached and float over the player character before throwing themselves at them, similarly to [[Ghost Vase]]s. A Ghost Block breaks apart and releases a [[coin]] if it hits the floor or a platform. Ghost Blocks 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 [[Blockhopper]]s from ''[[New Super Mario Bros.]]''
