A sandy track. There are 2 hidden paths that intersects at the beginning and the end of the track. They do sometimes a curve effect. You can build water towers on a juxtaposed sea. There are a lot of spaces to build a lot of Banana Farms. But of course, start popping the bloons! There is also a pink starfish near the bottom left corner of the sea.
