Super Mario 3D Land: S8-2

We need 240 Star Coins to unlock this level. This level has rotating green platforms that move much faster. We have to cross them and deal with Rocky Wrenches. We get the first Star Coin over the third rotating green platform from the Rocky Wrench that throws coins. We need a Tanooki Suit to get the second Star Coin (but, in general, it's a good idea to have one in this level). After the first Star Coin are some Rocky Wrenches and green platforms. We go to the left to find a Rocky Wrench in a pipe. This takes us to a large plaform with a brick block, which hides a gear. We need to spin the gear with our tail to move the platform up to the second Star Coin. We jump down to six Rocky Wrenches, some of which throw coins. Past them is a long platform that moves in an arc. We go the the far edge and let it rotate to the top. Don't jump at the first place you see: there's a Poison Mushroom there. The third Star Coin is down to the right of the last arcing platform. Jump down to get it. The Mystery Box will take you to an area with cutouts. The left Mystery Box will put you in a better position to get a 1-up at the flagpole. The right one will take you directly to the flagpole.
