As described previously in our strategy, Camo Bloons are troublesome, and only Dartling Guns and Spike Factories can see them without upgrades. Camo Leads are even more vicious. Try using Cannon Ships (if there’s water on the board), Flash Bomb Ninjas, Monkey Sense Apprentices, White-Hot Spike Factories, Meerkat, or Radar Scanner Village to Bomb Towers to take these out.
