New Super Mario Bros. U: Soda Jungle-3 -- Bramball Woods

The Bramballs return in these darker woods. You can see, but the background is darker. Approaching several of the Bramballs in the level will make blocks appear so they can move around. Like the Pokeys, the Bramballs can turn into fruit, but Yoshi isn't around to take advantage of that. There's an invisible block with a 1-up near the item block with the Fire Flower. The first Star Coin is over the void, between two sets of brick blocks. Wall jump to get it. The Ice Flower can freeze the Bramballs, which is handy. Nearby is a part of the level that has multiple tiers. Run on the second tier from the top to the right to a hidden area with the second Star Coin. Soon, you'll reach the midpoint. Go past the Walking Piranhas and you'll reach some donut lifts. There's a Green Ring, as well as the third Star Coin below. To get the Star Coin, stand on the donut lift and let it drop, then jump to safety once you have it. At the end, you'll see a mini pipe, as well as a regular pipe. The regular pipe is at the bottom of the level, guarded by Bramballs. This leads to the flag, which opens the path to the Mushroom House and the Fort.
