3DS Neo Bowser City

Neo Bowser City (known as Koopa City in Europe and Australia) is the third course of the Star Cup in Mario Kart 7. It is a neon-lit city-themed course owned by Bowser and his Koopa Troop. Neon signs are everywhere and Bowser's signature emblem can be seen in various places.

Description
The course takes place in a brightly lit, rainy city. Most of the course is winding roads with moving neon arrow railings. There is a small upward spiral that goes up a tower. There is a tunnel close to the end of the course that leads to a road that is covered with puddles. At the end, there is a ramp that uses the glider. If the player veers left from the starting line, they can go through an air current to propel themself upwards to cut the first S-bend; however, they must steer back in quickly to avoid hitting the wall in higher engine classes. This course's theme is a remixed version of Toad Circuit/Mario Circuit and the title theme of Mario Kart 7. It also contains remixed parts from the previous installments such as of Mario Kart 64's Toad's Turnpike and Mario Kart Wii's Luigi Circuit/Mario Circuit.

Layout
The course starts with an S-bend; however, they must steer back in quickly to avoid hitting the wall. After that, the race continues under a tower with air ducts. Then there are two soft turns and a red tunnel. After many turns, the player exits and reaches the winding part of the road, which consists of three turns. Then there is a shorter tunnel that leads to a road all to the left that is covered with puddles. At the end, there is a ramp that uses the glider and then the lap finishes.

Shortcuts
After the S-bend the player can cut through the mud with a Mushroom. However, they must steer back in quickly to avoid hitting the wall.

Trivia

 * This is the second course in the Mario Kart series that is placed in the rain, the first being Luigi Circuit from Mario Kart: Super Circuit.
 * This is the first course related to Bowser that is not a castle.
 * Metal Mario is this track's Staff Ghost in Time Trials, and not Bowser.
 * The billboard that appears near the starting line displays an image of Bowser. That artwork was first used in New Super Mario Bros. Wii.
 * At the very beginning of the race, just before everyone enters the air vent area, it is possible to be pushed through the guardrails by a heavier opponent. This causes the player to helplessly fall to the ground, as if they had fallen off of the course normally. Lakitu will then pick them up as normal and then place them just before the curve.
 * The "Overtake" ads found in Toad Circuit also appear here. However, they are animated and are shown on the screens of the track.
 * Being hit on the air current at the end of the track can result in only being able to move very slowly until booted from the game on Online Mode.
 * If the player uses a mushroom or uses the air current at the finish of the track,he can go in a secret zone on the S-bend,under the red tunnel,and he can do a shortcut,but is very difficult do it
