Pipe Plaza is a Battle Mode course selectable in Mario Kart: Double Dash!! and reincluded in Mario Kart DS. As its name implies, there are a total of four pipes for the drivers to teleport with from a lower ground to an upper wire mesh area or vice versa with the plaza being in a field of grass with large pipes coming out of the ground. There are a few Item Boxes around the course. Otherwise, it is as simplistic as the other battle courses of Mario Kart: Double Dash!!. In Mario Kart DS it is one of the smaller courses like Nintendo DS or Tart Top, giving out more havoc and smaller ranged attacks.
In Mission 3-5 in Mario Kart DS, entering the pipe at the upper left corner will spawn Yoshi at the pipe at the bottom right corner. This is likely to make getting to Gate 5 easier.
In the GameCube version, there is an animation glitch: if Daisy is in the back of the kart and she's hit by a fireball that knocks her into one of the pipes, her "getting burnt" animation will continue until she's hit again or until the battle finishes.
In an earlier version of Mario Kart DS, there was a sunset background instead of a daytime sky as in Double Dash!!. This was changed in the final version.
Also, if the player is next to the wall opposite the pipes, and they get hit by a shell, they may spin on to the little narrow ledge beside the at the bottom.
In Mario Kart DS, Pipe Plaza uses the same music for every other battle course in the DS version. The same also applies to Block Fort, a battle course from Mario Kart 64.
In Mario Kart DS, due to a glitch, it is possible to fall off the track when getting hit by an item such as a shell or a Bob-omb at the right moment while driving through one of the pipes.
