Piranha Plant Slide (known as Piranha Plant Pipeway in Europe and Australia) is the first course of the Star Cup in Mario Kart 7. It is based off of the underground levels of Super Mario Bros. It consists of floating blocks, two Gloombas, one Grand Goomba, and of course, Piranha Plants. Players have the option to drive on the floating bricks and collect the Coins on them.
Mario Kart 8 trivia: The course is updated to have ambient lighting and better shading.
