SNES Donut Plains 1

Donut Plains 1 is the second course in the Mushroom Cup of Super Mario Kart. It was later reused in Mario Kart: Super Circuit as the second track of the Extra Mushroom Cup, in Mario Kart DS as the first race of the Banana Cup, and in Mario Kart Tour, debuting as the featured course of the Hammer Bro Tour.

Course layout
The course features a lake which is to be crossed by a bridge. Though the major part of the lake is surrounded by crash barriers, there are some places where the player can fall into the water. Another obstacle of the course, alongside the fact that it is relatively curvy, is a large lake of mud just before the finish line, which makes drivers' control over their karts difficult.

Shortcuts

 * Turning right after the bridge, the user can boost across the grass patch.
 * After the first bend after the bridge, there is a gap in the crash barrier. Players can go through here to cut off a bit of the track.
 * Boosting through the large patches of mud around the corners can save some time.

Mario Kart: Super Circuit
In Mario Kart: Super Circuit, Donut Plains 1 is the second track of the Extra Mushroom Cup. It uses the background of Riverside Park. An item box has been added to the right side at the start of the second U-turn. The pipes on the side of the road have also been removed.

Mario Kart DS
Donut Plains 1 returns in Mario Kart DS as the first course of the Banana Cup. Like every other Super Mario Kart track in Mario Kart DS, it only has 3 laps instead of 5. The bridge at the beginning has been widened and the first mud patch is larger. The mud patches now slow down racers. The pipes are green, rather than orange. Mission 2-3 ("Drive through all red in order!") is played on this track with Donkey Kong being the playable character. Donut Plains 1 was never available in Wi-Fi mode.

Mario Kart Tour
Donut Plains 1 reappears as a classic course in Mario Kart Tour, debuting in the Hammer Bro Tour. It generally retains its Mario Kart DS layout; however, the walls within the course are thinner, and the barriers left of the bridge are absent. The bridge is also reverted to its original width. The gap in the wall after the second turn is shorter and moved right. The pipes are also gone, as in the Mario Kart: Super Circuit version of the course. The lake does not extend to the starting turn, and its two sides near the second U-turn are the same length. The brown hills in the background are also removed.

The course also appears as Donut Plains 1R (reversed), Donut Plains 1T (with ramps), and Donut Plains 1R/T (reversed with ramps); the first two were introduced alongside the normal variant in the Hammer Bro Tour, while the last was introduced in the 2020 Yoshi Tour. In the R/T variant, a glide ramp is added near the first shortcut.

This course uses the original version of its music, despite it being arranged in Mario Kart: Super Circuit, Mario Kart DS and Mario Kart 8.

Mario Kart DS

 * North American website bio: Super Mario Kart vets are sure to recall the twists and turns on this nerve-racking track. Stay focused, or you’ll get muscled into the grass.
 * European website bio: Sadly there are no sugary treats to be found here but Donut Plains 1 still makes for some pretty sweet racing. The layout is similar to Mario Circuit 1 but ‘donut’ be fooled into letting your guard down, as the trackside mud patches have caught many a driver unawares.

Mario Kart Tour

 * Mario Kart Tour Twitter: The rustic pastures and rolling hills of the SNES Donut Plains 1 course may appear peaceful at first glance, but these twists and turns will have your kart doing donuts! Here's a tip: hold on tight as you round those corners.
