Dart Monkey is a tower in the Bloons TD game series that started as a Dart Tower in BTD1 and is now called Dart Monkey in all subsequent hames. Dart Monkey appears in every BTD game as the first and cheapest tower a player gets unlocked. It also appears in all Classic Bloons series games as a main hero. The Dart Monkey is a small brown monkey with a single dart in its hand, that is capable to throw that dart and pop one bloon with it at a time. In BTD6 Dart Monkey was upgraded now popping two bloons and having the more 3D-like appearance, but its darts are still ineffective against Lead Bloons.
