Horseshoe Island

Horseshoe Island is an island appearing in The Wind Waker, and is located west of Outset Island. This island is unique in that it contains a miniature golf course. In order to clear the course, Link must both throw and blow the nuts with the help of the Deku Leaf into the holes near the flags; to do so, he uses the Wind Waker to adjust the direction of the wind, so that it favors the motion of the nuts. The young hero must be careful, though, for giant, spiky plants will be blocking his way in each of the holes. Once Link completes all three of the holes, he can drop into the grotto at the end to fight two Winged Mothulas and obtain a Treasure Chart (#8).

A second Treasure Chart can be retrieved by gliding to the center of the island using the Deku Leaf. A treasure chest will be there containing Treasure Chart #28.
