Double Double Cross

 is an expert track in Bloons TD 5 Mobile. There are 2 pools of water that appear to be acid. The entrances are in the corners, and double as exits.

Description
Double Double Cross is a mystical-looking map. All bloons enter from each corner and move towards their opposite corner as their exits. There are two pools of acid-like water that Buccaneers and Subs can be placed on. There are also a few brown ferns around the place and a purple cliff at the top and bottom of the map.

Trivia

 * The track's name may be a reference to the Double-Double burger from the fast-food restaurant In-N-Out Burger. The name may also be a reference to double-crossing, the act of betrayal.
 * This is the only map pre-BTD6 that is the same in reverse mode as in normal mode.
