~ Bloons TD 4 description

Dart Monkey is a monkey tower that shoots darts that can pop up to 1 bloon each. It can be upgraded to pop more bloons or have a higher attacking range. It costs $170 on Easy, $200 on Medium, $215 on Hard.


In BTD4, it, like all other towers in the game, has a revamped design. It still looks hand-drawn, but is now a more refined design.

The icon is no longer a circle with an indicator of the tower, and is instead, from this game and forward, the base monkey sprite.

In addition, the Dart Monkey has a premium upgrade called Exploding Darts wich makes each dart make a small explosion when they run out of pierce. The explosion does 1 [?] damage, has TBA pierce and has an explosion type damage, allowing it to pop leads. The effect disapears after buying spike-o-pult.

  • Their main use is on a cheap earlygame, as they are effective when spammed lower tiers to save up for farms.
  • Setting Spike-O-Pults to last on straightaways helps they maximize their pierce and can be helpful dealing with crouds
  • Triple Shot is really underpowered, costing 2k for a 1 damage tower with 48 pierce, this tower isn't recommended to be used.
  • Spamming lower tiers with Exploding Darts can add a lot of damage for a really cheap price.
