World 7-4 (Super Mario 3D Land)
From the Super Mario Wiki
Mario starts on a metal platform. After making it across some gears, he should jump across a swinging platform and three moving platforms circling before going into Morty Mole infested tunnels. After that, a Warp Box takes Mario to the Checkpoint Flag. Then after another gear, there are four L-shaped platforms, with the one at the bottom left having a Red Ring on it. The L-shaped platform at the top left leads to two more metal platforms, then there is another L-shaped platform and then there are those three circling platforms that take the player up to the Goal Pole.
