DS Wario Stadium

Wario Stadium is the first race course of the Special Cup in Mario Kart DS. The track has its own introduction music in the single-player Grand Prix. The course contains numerous mud puddles, speed boosts, jumps, twists, and fireballs. This version is more reminiscent of Waluigi Stadium than its counterpart and shares the same music to Waluigi Pinball. It returns as the first course of the Leaf Cup in Mario Kart 8, making it the first Wario-themed retro course.

Course layout
The course starts with a 180 degree left turn, followed by a right turn and a left U-turn. The player then climbs up a ramp and uses a Boost Pad to jump over the end of the course (A mesh platform prevents racers from falling down.). The player turns left into a mud pit that slows racers down. Boost Pads on island like roadway can help racers pass the area faster, as well as Mushrooms. Then racers climb up ramps with spinning Fireballs that act like a ring of fire. The path narrows and passes a mud pit with spinning fireballs being obstacles to the track. Next, racers climb a giant ramp before passing several small humps. Racers take one more U-turn before jumping off another ramp to the finish line.

Missions
Mission 7-5 takes place on Wario Stadium. The mission involves the player having to collect twenty coins in fifty-five seconds.

Mario Kart 8
Wario Stadium returns in Mario Kart 8 as the first course of the Leaf Cup. This course is the first Wario course to appear as a Retro Course. The course was upgraded to use the new gameplay mechanics of Mario Kart 8. For example, instead of continuing down the dirt path where the spinning fireballs are, the players race sideways on a giant tower on an anti-gravity section. Soon after, racers will encounter a newly made underwater section instead of continuing on the dirt path from the previous version, which then follows to a gliding section that lasts until the finish line, instead of a boost ramp. This part of the track, compared to the original section, has been modified to just a U-turn. The other major changes are an addition of the statue of Wario and the time of day, which has been changed from midnight to the afternoon.

The starting banner can be interacted with from playable characters, thanks to the hang-glider section at the end of the course. The course is one of three with this feature; the other two courses are Mario Circuit and 3DS Neo Bowser City.

Official descriptions

 * US website: "Hit the dirt in Wario Stadium, where huge jumps and bone-rattling bumps make for an action-packed race."
 * European website: "Wario's tricky track is just as tricky and dirty as the man himself. It's a bump-ridden speedway-style course packed with pitfalls like mud to slow you down and spinning wheels of fire to burn unwary drivers. How this passed the safety inspection we'll never know..."
