Where can you get a Tanooki Suit in Super Mario Brothers 3?

Where/how can you acquire a Tanooki Suit in Super Mario Bros. 3?

The Tanooki Suit gives you the ability to fly (like the leaf/racoon tail) but also gives you the ability to briefly turn into an indestructible statue. It looks a bit like a teddy bear.

WORLD 4

RED MUSHROOM HOUSE: Vends tanooki suits! Get one, they rule!

LEVEL 4-5: Later on, you'll see a brick in the sky. Bounce off the bullets to hit it. A vine will spawn. Do the same thing to get up to it and climb it. You get a tanooki suit! Hit the P-Block and follow the coins to safety.

WORLD 5

MUSHROOM HOUSE: Grab a tanooki suit now!

LEVEL 5-5: Whoever thought up this level should be shot! Go down the second pipe for a tanooki suit, but careful not to get any leaves or it goes to waste.

MUSHROOM HOUSE: If you're lucky, you get a tanooki suit.

WORLD 7

MUSHROOM HOUSE: This one is interesting. It only vends Tanooki suits, hammer suits, and frog suits. hehe.

FORTRESS: The fourth block on the top of that overhang is a P-Block. You can imagine what that does.... ;) However, it'll create a door which has a Tanooki suit ready for you. DO NOT get the fireflower or you're screwed. Time is of the essence on this level.

Choose the first box in World 5's mushroom house. It works every time.
