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 webs where a ? Block containing a Super Leaf can be found. This is followed by a Goomba and a Scuttlebug above Poisoned Water. Another Goomba and more 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 webs follow. After that, more webs can be found along with the third Star Coin. Climbing up the rest of the webs will then take Mario to the flagpole.
- Star Coin 1: When the player sees the first ! Switch, Mario needs to activate it by climbing the webs, being careful not to fall into the poison. Red blocks will then appear over the poison, allowing access to a yellow Warp Pipe on the left which takes Mario underground. Another ! Switch can be found in a Brick Block, which makes more red blocks appear. Mario will need to go towards the left to find a Scuttlebug and the Star Coin. Mario will then have to bounce off the Scuttlebug at the right time to obtain the Star Coin and avoid falling into the poison before the timer runs out. If Mario does not have correct timing, he can also wall kick to get the star coin without touching the poison.
- Star Coin 2: After the checkpoint, Mario needs to bounce off the second Scuttlebug to reach a yellow Warp Pipe. Warping through it will take Mario to a secret area. Mario will then need to activate a ! Switch on the ground to make several red blocks appear. He will then have to quickly climb up the blocks and bounce of the lone Scuttlebug to obtain the Star Coin.
- Star Coin 3: The last Star Coin is located below an orange platform in between two webs just before the flagpole. Mario needs to climb on the webs to reach the Star Coin while not falling into the poison.
