Waluigi Stadium (arcade)
From the Super Mario Wiki
Waluigi Stadium is a race course encountered in the game Mario Kart Arcade GP 2. As many other tracks from this game, this track takes place in the same location in Stadium Arena, but has a different route. Racers start in a dirt section of the track with high bumps, which then leads to a pit with green liquid and robotic dinosaurs. After this green pit is a chain ramp that leads to the top of the course. This road eventually leads racers back to the starting line. Just as Stadium Arena, this course has many robotic dinosaurs in it.
