Editing 3DS Piranha Plant Slide

The start of the track begins at a castle, from which players drive down three water slides that lead into a pipe with a sideaways and top entrance in the same fashion as [[World 1-2 (Super Mario Bros.)|World 1-2]] in ''Super Mario Bros.'' The track is mainly underground. It has flowing water that can cause the player to speed up when driven on, similar to [[Wii Koopa Cape|Koopa Cape]] from ''[[Mario Kart Wii]]''. There is a huge Piranha Plant in the middle of the road, which causes the track to split for a bit. After passing the Piranha Plant, two Goombas are encountered. Both are blue, similar to the underground ones in ''Super Mario Bros.'' A huge jump right after the Goombas leads the player to regular ground. Players also have the option to jump and drive on rows of floating bricks and collect [[Coin]]s on them before landing on the ground. A few pipes on the ground provide jumps for the player in the turns afterwards, which form a zigzag. Soon, the player must go down a huge pipe into a section that is [[Underwater driving|underwater]]. Some pipes are [[Jet Pipe|bubble-jet pipes]] that allow for players to be blasted to higher ledges. Another Piranha Plant blocks the path at the end of the tunnel, causing players to have to maneuver around it, though players can drive above it using the bubble-jet pipes. Then, players drive up a ramp which takes them above ground to a fortress with three [[drain pipe]]s that the player must avoid. They will land on a grassy area with walls, [[Horsetail]]s, and bushes heavily resembling the ''Super Mario Bros.'' backgrounds. Some [[Wooden cutout|board]]s shaped like Goombas and bushes are placed in the road, too, and there are gaps in the fences where players can use a Mushroom to cut through the grass before the finish line.

The biggest change done to the course is the alteration of the underwater section. The chute that enters the water now goes straight down and is wider, longer, and has three slides akin to the opening of the track, instead of being a small spherical hole in the wall. Several trick ramps while heading down the chute replace the trickable pipes found in the original version of the track. The chute and the underwater section are also now an anti-gravity segment, with the track going down and then sweeping upward towards the glide ramp through a large tank populated with [[Cheep Cheep]]s, rather than through a closed tube. This results in a much steeper Glide Ramp. The ledge reachable by way of a [[Jet Pipe]] has also been repositioned to rest in the center of the track, instead of along the right side; it now allows racers to jump over the Piranha Plant prior to the Glide Ramp.
