World 7-3, is the thirty-fifth level of Super Mario 3D Land.
In order to get to the large tree that makes up the majority of World 7-3, Mario must cross a tightrope hovered over by a group of Biddybuds. Jumping up the rest of the tree, Mario must quickly outrun and dodge several groups of Fuzzies. The teleportation block atop this first area takes Mario to the right side of the tree. This side of the tree is much smaller, featuring only a couple of Venus Fire Traps, but at the large wooden plank on this edge, Mario will find the level's Checkpoint. The final portion of the level sports numerous tightropes in several directions that Mario must use to climb to the top of the large, thin trees. After the trees, Mario finds the final teleportation block which leads to the level's Flagpole.
Enemies that appeared in World 7-3:
- Star Medal 1: The first Star Medal featured in the level can be obtained by walking past the first teleportation block and jumping onto the tightrope below, along a stream of coins.
- Star Medal 2: In the second portion of the level, Mario can hit the ↑ blocks to make a staircase to a colorful music block. This block will take Mario to Coin Heaven, and at the end of the Coin Heaven, Mario can find the Star Medal.
- Star Medal 3: After the second teleportation block, Mario must climb a large wall of tightropes, and here, Mario can find the blatantly placed, final Star Medal.
