Four O's

Loop-the-Loop is an Intermediate Track in Bloons TD6.

Overview
In a brownish mountains, the monkeys discovered a loopy track in it. They loop two times as they exit after they looped in it. The bloons starts to appear at the bottom and exits at the left. No water. You can't place the towers in the skies.

I REALLY FORGOT TO PUT THE S (START) AND E (EXIT) LOCATIONS IN THIS TRACK!
