New Super Mario Bros. U: Rock-Candy Mines-1 -- Fuzzy Clifftop

This level is crawling with Fuzzies. They're moving around on paths, but Yoshi or a Fire Flower can take care of them. You'll get Yoshi early on, and he's useful for dealing with the Ice Piranhas as well. You'll need your platforming skills to dodge Fuzzies while standing on expanding blocks, some of which move vertically. The first Star Coin is high above a vertically moving Fuzzy. Yoshi can bounce on the Fuzzies, so be sure to have him to reach it. Soon after is a series of expanding platforms that move vertically in the midst of a loop of Fuzzies. There are a couple of ways to go about this. You can have Yoshi eat the Fuzzies, which is time consuming, or try navigating the platforms with the Fuzzies zooming around. If you do the latter, you'll want to jump on the platforms when the first one is high, the second is low, and the third one is high. Once you cross that gap, you'll reach the midpoint. Next to it is a ferris wheel to a lower part of land. To the left of the ferris wheel, under a ledge, is a pipe. Be sure to bring Yoshi. The pipe leads to an area with lots of Fuzzies over a gap and a Fuzzy in a ring above, circling the second Star Coin. With Yoshi, bounce off the Fuzzies until you can jump up to get the Star Coin and return through the same pipe. Once you return, go to the left for an invisible area that takes you back up to the midpoint. Continue down the path with the ferris wheel. Ahead is an Ice Piranha. Have Yoshi eat this one, or another one ahead, but do not immediately breathe out the ball of ice. Under one of the rocks ahead are a bunch of Piranha Plants dangling from the ceiling and on the rocks below. Have Yoshi breathe out the ball of ice to freeze the first Piranha Plant. It will drop, crushing the Piranha Plant below it. This sets off a chain reaction that gets rid of all the Piranha Plants in the area. Carefully keep going to the right to reach the third Star Coin. After that is another set of vertically-moving expanding platforms in a loop of Fuzzies. Either have Yoshi eat the Fuzzies or dodge them to reach the pipe at the end. There's an invisible area below the pipe with coins. Reaching the flagpole opens the path to Rock-Candy Mines-2 and -3.
