Giddy Sky 7-9
From the Super Mario Wiki
At the start of the level, the player will need to use several moving vine platforms to get through the room. At the end of the room is the Warp Pipe. The next section is a zipline section with Perry. The next room has wind, and a switch that can change its direction. At the end of the room, if the player slides under the Warp Pipes, they can get another level for Toad Shot. After this is the goal gate.
