Piranha Plant Pipeline

Piranha Plant Pipeline is a course from Mario Kart Tour. It is an underground network of Warp Pipes. It will make its debut in the Pipe Tour. It is the second course introduced in Mario Kart Tour to be named after Piranha Plants, with the first being Piranha Plant Cove. This course's debut occurs only five hours after the debut of Squeaky Clean Sprint in Mario Kart 8 Deluxe, the shortest period of time between the release of two new courses (excluding courses that debut together).

Trivia

 * The course's appearance and concept are similar to that of the unused "dokan_course" from Mario Kart DS, both being named after Warp Pipes and themed around their traversal.
