Spy Bloon (Doue's Conception)

The Spy Bloon is a bloon that comes in at the beginning of a round. They go directly to a random tower, stay there for about 1 seconds, and dashes back to the bloons- as fast as a speedy purple bloon. Then, It dashes towards the exit at the same speed. These guys are ALWAYS camo. Do you know what they do at that random tower? They spy on it, exposing all it's weaknesses to the bloons. Every bloon is immune to that type of tower until you upgrade one of that type, unless it's fully upgraded, in which case the spying lasts only a round. This can be a very dangerous bloon. For instance, if you sold all your towers for super monkeys and only had a 0/0 dart monkey left... Oh, and you were on round 734 (A round where a spy bloon comes)...

These guys first appear at round 20.
