Boomerang Monkey (simply named the Boomerang in the beta tests) is a PrimaryMonkeycard in Bloons Card Storm. It deals 15 damage to the previous Bloon of the target Bloon on the opponent's Bloon track, if one exists. The second hit's damage is independent from its ATK and is unaffected by ATK modifiers, such as Divination or Weakening Gas Bloon.
Three Boomerang Monkey cards are unlocked by completing the Tutorial. Rang Bloons can generate Boomerang Monkey cards during a match.
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.
