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.
