A typical hole from Shy Guy Desert
Shy Guy Desert is a golf course played in Mario Golf for the Nintendo 64. It is the third unlockable stage and can be unlocked by obtaining 300 course points. The course is largely a desert, possessing bunkers, cacti and abundant sand. As a result, there are no water hazards. The Shy Guy Desert is the longest course in the game at 6706 yards, with the final hole being the longest. Every time a hole is completed, a silhouette of a Shy Guy's face briefly shows.
