World 7 (Super Mario 3D Land)

World 7 is the seventh world traveled to in Super Mario 3D Land. The setting of this world is a jungle-like area. The overworld's background is covered in purple haze and many trees, both big and small are spread throughout the background. World 7 contains 6 levels and a Toad House. Boom Boom and Pom Pom are both fought together in the airship at the end.

Overview
This level is reminiscent of World 3-2. Mario starts this level on a grassy area with flowers, a wooden pipe board and a Coin Coffer. Near of this place, there is a large pool of water. The goal is right ahead and can be quickly accessed by a Wall Jump on the wall, or the player may use a Tanooki Suit to cross the gap. Although, Mario must jump on the pool, to collect Star Medals. Mario must swim down, until reach in an area with some crates, two Cheep-Cheeps and a P-Switch. Pressing it, the wall on the right will reveal a passage. After crossing some Spiky Plants, the plumber faces two Porcu-Puffers guarding another passage. This passage splits into two. Swimming through the first opening, Mario can break many Brick Blocks to get a + Clock. In the second opening, Mario is taken by a stream to the Checkpoint Flag. Then, he must swim inside a U-shaped hollow, where are four Spike Eels and a single Porcu-Puffer. Mario will reach inside a dry area with a Warp Pipe, a Piranha Plant and Crates. The pipe leads Mario to the ending area, with more Warp Pipes, another Piranha Plant and the Flagpole.

There is, however, a huge shortcut that requires the Tanooki Suit. If the player goes on the far right side of the starting ground and jumps with the Tanooki Suit over to the other side, the player will be near the flagpole, making the game think the player has completed the level in 6-7 seconds.

Star Medals

 * Star Medal 1: Upon entering the water, the player should head to the bottom left. Behind the crates is the first medal.
 * Star Medal 2: The second Star Medal is found directly beneath the second Spike Eel of the column of the three. It can only be obtained if the Spike Eel is defeated or if it moves to attack while the player is behind it.
 * Star Medal 3: The final medal is found shortly after the second one. It's located inside a cave with another Spike Eel.

The first room contains many spiky rolls, two Chain Chomps and a Bottomless Pit with a narrow path, with more chained cylinders and an 1-Up Mushroom. Reaching on the other side, Mario must enter in a Door, that takes him to another area. In this area, soon after a Midway Flag, the plumber must cross a pink and blue tilting platform with rolling spike cylinders.

Overview
The level is a wood platform-based area, with several Grinders to slice the wood apart and potentially harm the player. The beginning point is on a wooden platform; on one end is a platform leading to the next wooden platform, and next to it is a platform with a Grinder ready to slice it off. After crossing several individual wooden platforms, the player reaches a cluster of them, with several Grinders and Goombas. The player must then cross through a pass composed of three wooden platforms about to be sliced off to get to one large wooden platform. Next to this is a wooden platform that rotates around to reach another platform, with several Grinders set at various points to chop off a segment of the platform. The next platform is followed by a cluster of wooden platforms with several Grinders to cut off each area of the platform. On the platform connected to this is the Midway Flag, and after crossing several wooden platforms to be cut off by Grinders, the player reaches a grassy platform. Afterward is a wooden platform traveling along a straight path, with several Grinders to cut off segments of the platform and poles to stop each segment and send it to the ground; there are also Paragoombas and some spikes. Afterward is a grassy platform with a wooden platform staircase and the Flagpole.
