Yoshi Falls is a race course in Mario Kart DS as the second track of the Mushroom Cup. The track is located in a crater-like valley, circling a lake with three waterfalls connected to the body of water, crossing the track. A large Yoshi Egg is found in the center of the lake. Numerous Dash Panels are located at some places along the course. Bridges do provide a safer way to pass, as opposed to going through the waterfalls is a risk, due to being able to be pushed off the edge. The missions 1-3 and 3-4 take place on this course.GCN Baby Park, N64 Moo Moo Farm, GBA Peach Circuit and SNES Mario Circuit 1. It is the shortest nitro course in the game. The track's overview is quite similar to Luigi Circuit from Mario Kart Wii.
Racers start far the edge of the cliff protected by a bar. As they go onwards, they can take either of the upper half of the track or the lower half, taking advantage to run faster but also being vulnerable to fall off or being pushed off by the rapids crossing the path. The upper level, however, has a bridge to cross safely over the waters, and handy Item Boxes. Racers then must take the second bridge, also containing Item Boxes. The stream of the second rapid down the bridge is more powerful, so it results easy to fall to the lake by taking this way. Certain item as a Star would serve to pass the obstacle and gain more time. Briefly, past the second bridge, characters can run over useful Dash Panels in the upper half, while the lower half has none of these speed boosters, some Item Boxes appear down the third bridge, unlike the upper stretch which does not have any. Once passed the bridge and the Dash Panels, the track ends in the finish line, which starts another lap of the course. This final stretch is a good oppotunity to perform a wheelie.
There are two missions involving this circuit: 1-3 and 3-4. In mission 1-3 the player has to destroy the 10 item boxes and in mission 3-4 they have to cross the finish line in a single lap before Yoshi.
