Yoshi Circuit is a course in the Star Cup of Mario Kart: Double Dash!! and of the Lightning Cup of Mario Kart DS. It is the third one in the Star Cup and the final one in the Lightning Cup respectively.
The course is unique in that it is shaped like Yoshi himself. Many turns are in the course, including a particularly sharp hairpin turn located at Yoshi's "tail". There is a straight area in the middle of the course, that is perfect for item traps. There are also a lot of Piranha Plants at the side of the road, nipping at racers who get too close.
 Course layout
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 the DS version.
 Appearance in 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. 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 Yoshi Copter not being present, and the banners near the finish line being removed.
