Instructions
Go to the sand dune next to the lighthouse. Several yellow, glowing dots cover the sand dune.
Tap the on-screen hand icon to switch perspective. In this perspective, you can use the stylus to draw a shape in the sand.
Touch the stylus to one of the gold dots. Drag the stylus in a circle, connecting the gold dots as you draw. After you draw a circle, draw a vertical line from the bottom of the circle. You get a gold balloon.
