Covert Pops (Special Mission)/Strategies

As all the bloons (excluding MOAB-class ones) spawn as camo, your top priority in the early rounds needs to be camo detection. Ninja Monkeys, Dartling Guns, a Spike Factory and Signal Flare Mortar Towers can help in the early rounds, and MOAB Maulers/Assassins in the later ones.
