Dune Sea

Dune Sea is an Advanced track in Bloons Tower Defense 5 and an Intermediate track in Bloons TD 5 Mobile. It was released on Feb 7th, 2014, followed with Water Hazard, an Advanced track (Intermediate in Mobile).

Overview
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.

Differences between Flash and Mobile
Dune Sea is now categorized as an Intermediate track instead of an Advanced track.
