DS Waluigi Pinball

Waluigi Pinball is the third race course of the Flower Cup in Mario Kart DS. As its name implies, this course takes place in a giant pinball machine themed after Waluigi and contains many sharp turns and curves.

Mario Kart DS
Soon after the countdown ends and the race begins, the kart drivers are launched into the pinball machine. After that, the racers start a descent down the machine, encountering numerous metal balls on the way. Colliding with one of these causes drivers to be knocked backwards. Additionally, a racer loses any items they may be carrying. While the racers are in the pinball launcher, they are immune to all items, including Lightning. Later in the track, inside the pinball area, there are flippers and bumpers. Bumpers push and speed up drivers, but flippers, when moving, can cause them to get electrocuted and spin out.

Missions
There are two missions involving this circuit: 3-1 and 4-7. In mission 3-1 the player must break 5 item boxes and in mission 4-7 they must drive through the 10 gates in any order.

Staff ghost
The staff ghost in this track is 2:23:288 using Waluigi in the Gold Mantis.

Mario Kart 7
MK7-DS-WP.png The track returns as a retro course in Mario Kart 7 as the fourth and final course in the Banana Cup, despite Waluigi's absence. The layout remained the same, but with enhanced graphics and the Dash Panels are now orange.

The launch after the start/finish line now encompasses a gliding pad, although like Maple Treeway and Airship Fortress, players cannot aim their flight. Players are also no longer immune to items while in the launcher, and being hit by anything (or stowing their glider) results in having to be rescued by Lakitu. The jumps after turn 1 and after turn 6 can be used to perform a trick and gain a boost. An extra Dash Panel is added in the small drop near the circular turn that comes after the 2nd jump.

The pinballs, bumpers, and flippers on the table behave the same way as in the DS version of the course. While playing local or online multiplayer, only one pinball traverses the main table as opposed to two.

Mario Kart Tour
Waluigi Pinball returns in Mario Kart Tour, with several aesthetic differences, including the image of Waluigi's head now rotating left and right.

Official descriptions

 * Mario Kart DS European website: "Wario's weird sibling constructed this high-speed track inside a giant pinball table; complete with bumpers, flippers, ramps, and enormous steel spheres that bounce you around like - well, like a pinball. Make sure to bring plenty of aspirin for this race."

Music
Waluigi Pinball shares its music with Wario Stadium. An arrangement of the music is also featured in Super Smash Bros. Brawl and Super Smash Bros. for Wii U on the Mario Circuit stage, and in Super Smash Bros. Ultimate for any Mario Kart-series stage, arranged in an enhanced electronic rock style by Kentaro Ishizaka. The arrangement also incorporates Wario's victory theme from the same games.

Trivia

 * In Mario Kart DS, this course shares its Grand Prix introduction fanfare with Figure-8 Circuit, Mario Circuit and GCN Luigi Circuit.
 * The course has several unique sound effects that evoke pinball machine scoring noises. These sounds are carried over to its retro course in Mario Kart 7 and Mario Kart Tour:
 * A unique item roulette sound, making it one of four courses in the series to have a unique such sound, with Hyrule Circuit, Animal Crossing, and Urchin Underpass (all crossover courses) being the other three.
 * An additional "rolling" sound played when traversing a Dash Panel. No other course in the series has this feature.
 * A unique set of sounds for when the player's position changes. No other course in the series has this feature, though similar sounds for when the player's position changes are used in Mario Kart Wii onwards.
 * Except in Mario Kart Tour, where the second lap is the final lap, a unique jingle plays when the player enters the second lap. No other course in the series has this feature.
