World 3-3 (New Super Mario Bros. 2)
From the Super Mario Wiki, the Mario encyclopedia
World 3-3 is the first level taking place in a jungle in World 3 of New Super Mario Bros. 2. This level can be unlocked by completing World 3-2. The only exit in the level unlocks World 3-. The level introduces webs which the player can cling on to, simillar to the mechanics of the fences. However, Mario will fall when he holds on to the web for too long.
Mario begins in front of two spider webs where a ? Block containing a Super Leaf can be found. This is followed by a Goomba and a Scuttlebug above purple toxic waters. Another Goomba and more spider webs can be found, where a ! Switch can be seen (see Star Coin 1). This is followed by more Scuttlebugs, along with the checkpoint. More Scuttlebugs and spider webs follow. After that, more spider webs can be found along with the third Star Coin. Climbing up the rest of the spider webs will then take Mario to the flagpole.
