Thirsty Gulch
From the Super Mario Wiki
Thirsty Gulch is a board in Solo Mode from Mario Party 6. The setting here was a desert mesa above a canyon. The inhabitants consisted of Goombas that watched player's progress, Piranha Plants that were doing a jig as if they were from Pop-Star Piranhas, and Klepto, who flew around the higher area of the board. The board was mostly made up of 2-Vs-2 Spaces.
Landing on the ? Space caused the slab underneath to fall off, sending players to the lower section of the board. If a player went past the last space of the board, they stopped at the edge of a cliff. The cliff then crumbled beneath them, and they ended up falling Wile E. Coyote-style into the river below, losing everything.
