The Boomerang Monkey (referred to simply as the Boomerang in the beta tests) is a PrimaryMonkeycard in Bloons Card Storm. It deals 25 damage to the target Bloon and 15 damage to the Bloon behind it in the opponent's Bloon queue if one exists. The second hit's damage is independent from its Attack Power and is unaffected by Attack Power modifiers, such as Divination or Weakening Gas Bloon.
Three Boomerang Monkey cards are unlocked by completing the Tutorial.
Boomerang Monkey can also be created from Rang Bloon.
The Boomerang Monkey is outclassed by other early-game monkeys, as it only has 25 damage per turn against single targets, or 40 if two or more bloons are on screen. In comparison, Mortar Monkey costs 1 less but does the same damage per turn against a random target, or Dart Monkey Twins which take up 1 more tower space and is 1 gold cheaper than Boomerang, but do 10 more damage per turn, and Triple Shot does 20 more total damage against 3 targets while doing the same total damage versus 2.
