World 1-3 (Super Mario Bros.)

World 1-3 is the third level of World 1 in Super Mario Bros. It involves maneuvering on large trees.

Layout
Through a small ground area, Mario will reach a giant tree that can be used to reach two more trees, containing a Koopa Troopa and three Coins. Ahead, three trees are used by two Goombas. On the top of the third and taller tree, a shorter tree can be reached. There will be a platform that can help Mario to reach the top of a tall tree with four coins. Under this tree, a shorter one contains the only Question Block of the level that contains a Super Mushroom or a Fire Flower, depending on Mario's form. There will be a short tree and a taller one, that is used to reach a tall tree that contains a Goomba. Between these two trees, there's a Koopa Paratroopa. There will be two platforms that will go side to side. There will also be some Coins. There will be two trees, the first one is small and of medium width, while the other is wide and tall. There will be a Koopa Troopa in the taller one. A short tree with three coins is under a Koopa Paratroopa. There will be two similar trees that can be used to reach a platform. The platform can help Mario to reach a Block wall. The Flagpole will be after it.
