Bowser's Villa 8-4
From the Super Mario Wiki
The level starts off in a section where Perry must be used as a zipline. Directly after this is a Subrella section. After this is a room with Cannons and some Robotic Arms that try to grab the player, and explode on them. Midway through this room are some blocks that can be destroyed to get to a Warp Pipe. This Warp Pipe leads to a room that can be rotated 90 degrees by some blocks. At the end of the previous room is a Warp Pipe that leads to a similar room that can rotate, just with Mad Big Boos instead of Mad Boos. At the end of the room with the Mad Big Boos is a Warp Pipe that leads to the first Toad, and another section where Perry is used as a zipline.
After this is a room with a hot-air balloon, that needs to be powered by using the Rage vibe, to the left of the room is another Toad, and a door. To the right is a Warp Pipe. In the next room are large spiked balls, and some moving stone platforms, midway through this room, if the player goes down along some platforms they will get to the final Toad, before getting to some Hammer Bros. At the end of the room is a Warp Pipe that leads to the rotating room that has the Mad Boos. If the player goes through the door in the hot-air-balloon room they will enter a room with Donut Blocks and Podoboos that eventually leads to a door. After this is a room with several Fire Bars, before the goal gate.
