|“||Steep canyons and a very large egg... Hmm... How does this course relate to Yoshi? To make one lap, you can take any route you like through the complicated maze, but without keeping a careful eye on the course radar, you might drive the wrong way and end up returning to where you started. Of course, leaving the course is forbidden.”|
|— Instruction manual description • Mario Kart 64|
The obstacles for this track include Spinies, which are scattered around the track to slow down players. Near the end of the stage, a giant Yoshi egg rolls about. If a racer is unfortunate enough to collide with the egg, they will be flattened and rendered unable to move for a few seconds.
This stage has so many winding paths that the game can not read the current standings until the end of the race.
Yoshi Valley makes a comeback in Mario Kart 8, where it is pretty much the same, only that it is in HD and the standings are correctly identified in-game.
