Activation of a Vanishing Block

A Vanishing Block is a block that appears in Super Mario Advance 4: Super Mario Bros. 3's World-e. It appears in one level, A Sky-High Adventure. Though the block is entirely solid and inert, it is invisible under normal circumstances. To make it visible, Mario must use a Tanooki Suit (one is hidden in the level) to become a statue.
