This minigame come from MP1 and MP2 with the same concept but different layouts. Dungeon Dash also has another obstacle. The Desert version is from MP1 and the Dungeon version is from MP2.
The aim of this minigame is to tilt you control stick either left or right (whatever side you are on) and then your partner will do the same. You have to do it simultaneously though. Do that as fast as you can and be the first one past finish line/exit.
This was an interesting minigame but fun. When I versed another human player it was always close.
