Roller Coaster Rampage is a race course that's new to Mario Kart: Mega Mash-Up. It appears in the Bob-omb Cup.
The course is set on a new roller coaster in Pinna Park. It is similar to both Rainbow Road and Wario's Gold Mine in style with various dips, turns and uphill sections. It is a very colourful coaster and there are a couple of roller coaster carts going the opposite way to the racers and in order to avoid them, the drivers must go to the edge of the track to avoid them.
