World 8-1 (Super Mario 3D Land)
From the Super Mario Wiki
World 8-1 is a fort-themed level with sunset background. The level starts out in a base with some Spinies and Spiked Ball shooters. Climbing a wall, Mario will find a space with two Fuzzies, Coins and yellow Elevators, which lead to a bridge where Giant Spiked Balls roll on, and two Donut Blocks at the end of it, just before a Warp Pipe. It takes Mario to an escalator guarded by Spiked Balls and two Spinies. Above the stairs, there is the Checkpoint Flag. Ahead, there is a two-story corridor. The first one is made of Reversible Platforms and more Spiked Ball launchers. The second corridor (which can be accessed via a Brick Block), has stationary solid floor and contains some ? Blocks and also the rare ? Box. A pole and a Warp Box are seen on the far right. This Warp Box transports Mario to a long downhill protected by Spiked Ball and Giant Spiked Ball cannons. Crates difficult the transition. Reaching the end, Mario can get in either a Warp Pipe or a Cannon, as both can be used to reach the flagpole.
