Yoshi Circuit is the third racecourse of the Star Cup in Mario Kart: Double Dash!! It reappears as the fourth of the Lightning Cup in Mario Kart DS. It also appears in the first DLC pack for Mario Kart 8 in the Egg Cup.
The course is unique in that it is shaped like Yoshi himself, making it the only track in the Mario Kart series to be shaped after a playable character. Many turns are in the course, including a particularly sharp hairpin turn located at Yoshi's "tail". There are also many Piranha Plants at the sides of the road, nipping at racers who get too close.
The race first starts at the straight road under Yoshi's "shoe." As the racer progresses for a little bit, the player will make a slow curve to the right. Piranha Plants are present on the grass on the right of the course, and to the left, there is water that will stop the player in their tracks if fallen off. Past the curve is a short straight road and a turn left. After the turn left is another straight road and soon, another curve to the right, which would be going around Yoshi's "hands". After the "hand" curve is a straight road, and another turn to the right that leads to an overhang, which starts a large curve around Yoshi's nose.
Inside the curve in Yoshi's nose, the player is protected by walls to the right to prevent them from falling into the water. Past the long curve to the right in Yoshi's "nose" is a sign that the player will see to turn left, obviously initiating for the player to turn left. The player will then make a shorter curve to the right around Yoshi's "eyes". Past Yoshi's "eyes" are his "scales", which are basically small and short curves around circular flowerbeds which won't pose the player much of a problem if the player correctly drives straight.
Past the orange flowers is a Piranha Plant, and past that Piranha Plant is a slight downhill change of terrain and a U-turn to the left. Past the U-turn is a small incline and a straight road, as one is progressing the "tail." On the tip of the "tail" is a U-turn to the right and a straight road. The straight road leads to a turn to the left and three Piranha Plants. Past the Piranha Plants is a turn to the right and a straight road, indicating that the finish line is just in front of the player and starting the cycle of the course again, but on the next lap.
There are two shortcuts. After the first left turn, if a player gets a Mushroom from an Item Box, he or she can use the Mushroom to jump over the moat, not having to maneuver around Yoshi's "hand". It is also possible to do this without a mushroom, instead using a well-placed powerslide. In the DS version, however, the shortcut can be done with a well placed jump over the moat if the player is using a high acceleration kart.
The second shortcut comes right after the tunnel, and it requires the player to use another Mushroom to propel themselves from the course into a tunnel, which emerges into a straightway. There are also Double Item Boxes in the tunnel. This second shortcut is removed in both DS and Wii U versions.
Mario Kart DS
Some edits have been made to the course for its reappearance in Mario Kart DS. The most significant change is that the Piranha Plants are no longer in Warp Pipes and bite at racers that drive too close, instead being the small, constantly-biting variation that is seen throughout other courses. Another somewhat significant change is that the number of spikes on the back of Yoshi's head have been reduced from three to two. Some minor graphical changes that do not impact gameplay include Yoshi's "fingers" not being there, the windows in the tunnel being larger, Yoshi's "cheek" being made of sand instead of water, the helicopter not being present, the second shortcut being removed, and the banners near the finish line being removed. The course was available in Wi-Fi.
Mario Kart 8
Yoshi Circuit appears a second time as a retro track included with the The Legend of Zelda × Mario Kart 8 downloadable content in Mario Kart 8 as the first course in the Egg Cup. Many changes have been made in this version of the track. The course now features a small town near the starting line, with a dock, several small islands and sailboats nearby also the Yoshi Bike appears to the right of the start/finish line. There are fewer Piranha Plants (although the ones that do remain have been re-positioned) and the Yoshi Helicopter has been replaced by a green Mario Kart TV helicopter, from the view above the course. The second shortcut has been removed entirely similar to the DS version, while the first shortcut has a waterfall which players must drive through. Yoshi's saddle now acts as a place to shade spectators. Also, a sign saying "Yoshi Tunnel" can be seen on both ends of the tunnel at Yoshi's nose. Also the course is more straight and the dips and inclines at the scales and the saddle has changed. The Ribbon sign featuring Birdo has been replaced by a Mario Motors sign.
A Tourist Information building can also be seen near the starting line, with posters for Toad Harbor, Water Park, Bone-Dry Dunes, and Sweet Sweet Canyon plastered on the windows. There are two chalkboards seen on buildings near the starting line that have team names on them, the teams being Mario Super Motor Team, Luigi Gusters, Toad Mushroom Powered, Yoshi Runners, Lord Bowser, and Princess Peach.
