Beanstalk Island is one of the special locations Navi-Sprite can take you. It is unlocked when you find 60 Follower Sprites.

The Sky Sprite will let you play the mini-game Digging for Sprites. The mini-game consists of three rounds where the player must dig up Gold Sprites and avoid digging up beanstalks. You can play this game multiple times in one day, but each session will make 1 hour go by. The number of Sprite Coins you receive will depend on the points you earn. If you earn 55 points or more you will be rewarded with two extra hearts of stamina.
