The Coo-Coo Course is a golf course in Mario Golf: Advance Tour located close to the Palms Club and the Golf Clinic and near the Links Club. The Coo-Coo course can be unlocked once Neil and Ella win against Azalea and Tiny in the Dunes Doubles Match, which can only be played in Story Mode. The Coo-Coo Course only has 1 hole, which is a par 5 hole that is 520 yards (1548 ft.). The course can be practiced, but with only one shot. There is a Cabin which upon entering, it is called the Coo-Coo Course Office. When the player enters the office for the first time, Grampie is seen laying on the bed, and talking to Grammie, she'll say that if the course is completed in a par or better, Grampie would feel like himself again.
