A Sky-High Adventure

Tanuki Suit no Himitsu (The Tanooki Suit's secret) is the 14th and Japan-only World-e level in Super Mario Advance 4: Super Mario Bros. 3. The level is based around several rooms linked via doors on a large tower. The level also introduces a new ability for the Tanooki suit, whereupon turning into a statue makes Vanishing Blocks visible and also introduces Grey Brick Blocks (breakable by a statue stomp or a Hammer) to the game.
