3DS Toad Circuit

Toad Circuit is the first race track in the Mushroom Cup of Mario Kart 7. It takes place at a basic circuit where giant balloons of various Toads are seen floating throughout it. This course is the "main" recognized course for Mario Kart 7, as it is recognized on the cover art of the game. This track shares its music with Mario Circuit. The award ceremony also takes place on this course at the end of every cup. This course reappears in Mario Kart Tour in several tours, beginning with the New York Tour, and in the Booster Course Pass DLC for Mario Kart 8 Deluxe, as the second track in the Golden Dash Cup.

Course layout
The course is a simple circuit with few obstacles, as it is the first course in the game and is comparable to Luigi Circuit of previous installments. There are a couple of long boost turns along the track and a couple of boost ramps which allow for the use of gliders, plus a bridge that the player can drive under or hang glide off a ramp and over the bridge and the ramp rises and closes from the ground up for usage after 40 seconds (although if they fly into the perpendicular track, it is considered out-of-bounds), as well as having a tunnel to drive through. Giant mushrooms are seen through out the track in different sizes and three large balloons of Toads (red, blue, and yellow) are floating along the track as well. Banners of Toad himself can be seen throughout the course with the accompanying Mario Kart logo. There is a big turn, then there is a ramp, where the player can use their glider. Then there is a tunnel, two more turns and then a big curve where lots of coins can be collected before crossing the finish line to start the next lap.

There is a pair of toadstools displayed on the touch screen map that are not present in the actual course itself; these were restored when the course was remade for Mario Kart Tour.

Shortcuts
Near the big curve there is a ramp where the player needs a Mushroom to cross. Also, after the ramp there is a dirt area with pipes that the player can cross by using a Mushroom. The player can also cut the first turn using three Mushrooms.

Glitches
There is an Item Box glitch in this course in Mario Kart 7. It involves using the Glide Ramp which is accessible on laps 2 and 3. The player should glide to the right, where there is a row of Item Boxes on the bridge, and swoop down to collect one without going too close to the road and being counted out of bounds. When the player does this, the game will assume for a fraction of a second that the player is all the way back at the bridge and thus momentarily changes their placement to last (unless another player is even further behind). By quickly returning to the track after the bridge, and not flying towards the Toad balloon on the right which will also count the player out of bounds, a player in any position can therefore hold very good items.

Mario Kart Tour
Toad Circuit reappears in Mario Kart Tour. The course is played for the tutorial, and when an update is being downloaded. This effectively makes Toad Circuit the flagship course of the game, as players can drive around in it in every tour, even when it does not appear in one. In the version that can be played when downloading updates, there are ramps before the tunnel. Other than graphic improvements, the course remains almost the same as its original appearance. This course is a favorite of Toad, Toadette, Hammer Bro, Blue Koopa (Freerunning), Peachette, Black Yoshi, Nabbit, King Bob-omb, Toadette (Explorer), Dr. Mario, and Kamek. This course is also a favorite of Metal Mario, Peach (Wedding), and Dr. Peach if they reach level 3, and White Yoshi if he reaches level 6. Like all other courses, this course has a reverse variant, trick variant, and reverse/trick variant named Toad Circuit R, Toad Circuit T, and Toad Circuit R/T, respectively. The R/T variant first appeared in the New Year's Tour.

Mario Kart 8 Deluxe
Toad Circuit returns in the Booster Course Pass DLC for Mario Kart 8 Deluxe as the second course of the Golden Dash Cup. It is largely identical to its appearance in Mario Kart Tour, except there are now Mario Kart TV trucks in the off-road areas, and certain aesthetic details have been updated, with the Toad balloons having their hands fully modeled and the Mario Kart logos on the signs throughout the track being rendered in 3D instead of being flat textures. There are also now tires in some offroad sections that can be hit, much like GBA Mario Circuit.
