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 contain many sharp turns and curves. The track's theme is shared with Wario Stadium.

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 pinballs on the way. Colliding with one of these causes drivers to be knocked backwards. Additionally, a racer will lose any items he or she 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.

Waluigi Pinball makes a cameo appearance in the Nintendo Monopoly board game. The music theme from the course is also featured in Super Smash Bros. Brawl and Super Smash Bros. for Wii U on the Mario Circuit stage arranged in a enhanced electronic rock style by Kentaro Ishizaka.

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.

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.

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 intentionally stowing their glider) will result 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.

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

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."

Trivia

 * This course shares its Grand Prix introduction fanfare with Figure-8 Circuit, Mario Circuit and GCN Luigi Circuit.
 * The "Waluigi Pinball" cover version from Super Smash Bros. Brawl has a section where Wario's victory theme is played (from the same game).
 * The course has several unique sound effects that evoke pinball machine scoring noises:
 * A unique item roulette sound, making it one of three courses in the series to have a unique such sound, with Hyrule Circuit and Animal Crossing (both crossover courses) being the other two.
 * An additional "rolling" sound played when traversing a Boost Pad. 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.
