World 1-3 is the third level in World 1 of New Super Mario Bros. 2, and it is the level that introduces the Super Leaf. This level takes place in the overworld, and has multiple trees you can get on by using the Super Leaf. This level also contains some Snake Blocks, Goombas, and Koopa Troopas.
- Star Coin 1: Once you reach the first runway, run down it with a Super Leaf, then start flying upward. Follow the coins, then get on top of the tree. There should be the Star Coin on the tree.
- Star Coin 2: After the first Star Coin's tree, fly to the next tree, then go down the Warp Pipe. This Warp Pipe will launch you to a bonus area. Use the runway in this bonus area to fly using your Super Leaf to get the Star Coin.
