Mario Kart 8
The track starts in a place near where six tents are set up. Toads can be found here, cheering the racers on. The will then start to split up, with a choice of green (Going downwards) or yellow (Going upwards). The tracks rejoin inside of a cave with two shortcuts (One on the right, near the start, while the other one is near the exit, on the left). The tracks separate outside, and start to go upwards for a bit. After this, there is a glide panel, taking you back to the starting point.
