World Flower-2 (New Super Mario Bros. 2)
From the Super Mario Wiki
This level takes place in a forest, where poison can be found with a Porcupuffer swimming in it trying to attack Mario. The level begins with Mario on an elevated platform beside a vine which is constantly swinging at the start of the level. Mario needs to swing on the vine to cross over to the other side and then drop off the cliff to the ground. Before the cliff a ? Block can be found containing a Fire Flower. On the other side of the cliff a Hidden Block containing a Super Star can be found directly above a Multi-Coin Block. Moving forward, Mario must then cross a gap, then a red Koopa Paratroopa and a red Koopa Troopa can be found on another orange elevated platform. Mario then has to cross the toxic water again with a vine. This is followed by a set of four Scuttlebugs and a Koopa on the ground. Mario then needs to cross more toxic water with a vine and the checkpoint follows. Another Fire Flower can be found in another ? Block. Mario then crosses the toxic water with a set of paddle wheels, while avoiding the Porcupuffer. On the other side, a multi-coin Block can be found with a red Koopa. Mario then needs to swing on another vine to reach another set of rotating platforms to cross the toxic water. More elevated platforms can then be found, followed by a Koopa and a Scuttlebug. On the other side, a Koopa can be found, followed by another vine with a Red Ring in the middle. A Paratroopa can be found, then Mario has to climb up a ledge and get to the other side, where a Koopa can be found which can be used to release a P Switch from a Brick Block. Activating the P Switch causes Blue Coins to appear. Mario then has to cross a large gap of toxic water by swinging from vine to vine, and then bouncing from Scuttlebug to Scuttlebug to reach a green Warp Pipe. Warping through takes Mario to the last area, where two Scuttlebugs can be found, followed by a high vine which can help Mario reach the top of the Goal Pole right after.
