Donut Plains 3

Shortcuts

On every single turn in the track, you can use mushrooms to boost through the grass. This works best on Turns 1, 2, 5, and 6.
On Turn 2, you can drift while jumping off the ledges to skip across the grass.
On Turn 3, you can do a tighter turn by staying in the water.

Donut Plains 3 is a good bagging track due to the grass shortcuts.
Golden Mushrooms and Bullet Bills can be used after the second set to speed past the final shortcut while also running out before the first set.
Shocks can be very punishing when chaining into the second set.
Some good trap spots are on the bridge, right before the second set, and on the S turn after that set.
