Wavy Beach 5-2
From the Super Mario Wiki
The level starts out by a slope that leads to an area where the player must use some beach balls to destroy some blocks, so they can progress. If the player uses the Joy vibe, just before going down the Warp Pipe to the next area, they can float up to an area where there are several Green Koopas.
The next area has quicksand and various enemies. When the player gets to the water section, if they use the Joy vibe they can get to a giant Springboard and a water geyser, which the player will also have to use the Joy vibe on to make it shrink, so they can get to the first Toad. During the water section, the player will find the Subrella, underneath a Warp Pipe. The next Warp Pipe leads to the next area.
This section takes place underwater and uses the Subrella, before leading to a Warp Pipe. After this, the player will be on land again, and they will have to avoid Big Chain Chomps, before getting to the next Warp Pipe. The next area has more quicksand and Pokeys. After the quicksand, the player will need to use the Rage vibe to burn some wooden platforms to get another Toad, before using the Joy vibe to get a water geyser to shrink, so they can progress. They must then climb a platform, with a Volcano Plant on it, to reach the next Warp Pipe.
The next area has more quicksand, underneath the second patch of quicksand is a Warp Pipe that leads to an area with some ! Clouds and the goal gate. Underneath the third patch of quicksand is the final Toad.
