Click Camo is a new bloon property. Bloons with this property cannot be detected by any towers until you have clicked on them. Some bloons may have stronger Click Camo, and may need to be clicked multiple times in order to be detected. Other bloons may have Click Camo that regenerates, and that thus need to be clicked again in order to continue to be detected after a certain amount of time. There will also be "Right Click Camo" and "Center Click Camo", but bloons will only have Center Click Camo if you have a mouse with a center button.
