Dart Ape is a special agent, unlocked for purchase after completing Diagonal on hard and then purchased for 350 monkey money. Dart ape when placed behaves similarly to an ordinary dart monkey, but the more bloons that he pops the stronger his popping power gets. If he pops 10 bloons in a round each dart will pop 2 layers, 20 equals 3 layers and so on capping at maximum popping power of 10 layers per shot. The pop counter is reset when each round is completed. In order to Pro version, you must buy it 60 times. Pro version allows double money gain in its attack radius and a passive 20% firing speed upgrade.
