Wild Woods is a track found in the Animal Crossing x Mario Kart 8 DLC Pack for Mario Kart 8.
The track starts out with the karts sideways, going up a tree. After a turn, you'll go through a fork. The right fork has jumps on it, while the left fork is simpler. Soon afterwards, you'll go through a town populated by Shy Guys (The houses also look sort of like Shy Guys too).
After this you'll enter a log, that's got a path of water you ride down on. The water will pour into a frog pond, with lily pads that have jumps on them. You'll re-enter onto the anti-gravity section taking you back to the finish line.
