Gleam Glacier 6-2
From the Super Mario Wiki
The level starts off with some Parabombs and some platforms, to the right of the platform section is a Warp Pipe that leads to a small room filled with coins. Going down the platforms will lead to a small uphill section with Bob-ombs blocking the way, before the Warp Pipe. The next area starts off with the first Toad underneath the player. The player must then use the Joy vibe to navigate a section filled with icicles. If the player uses the platform above the next Warp Pipe, they will go to a section with a Warp Pipe that leads to a secret room. In this room, the player needs to destroy a snowman and then go through the room, defeating various enemies, before melting some icicle creatures to get another Toad, before a Warp Pipe.
This Warp Pipe leads to a Subrella section, which leads to a Warp Pipe that goes to a room with a Puzzle Piece, which can be gotten if the player uses the Joy vibe. The Warp Pipe at the end of this room leads back to the room with the crevice that the player needed to cross earlier. In the room with the Calm Hammer Bro, if the player goes down the Warp Pipe instead of going across to where they get the Toad, they can go to another room that has a green ball that can be used to get the final Toad, the player then needs to get to the end of the room with the goal gate is.
