It functions almost identically to Bomb Bloon but grants a Boomerang Monkey. However, the Rang Bloon is much weaker than the Bomb Bloon despite Rang Bloon's lower rarity; Boomerang Monkey costs more than Bomb Shooter, lacks utility and initial burst of damage, and has poor single-target damage.
Although it can create up to two Monkeys for one card slot, and is a 1 delay Bloon each costing 1 Gold, building defenses from only Boomerang Monkeys is not recommended. By the time Boomerang Monkeys are ready to be played, 1-delay aggro and early Large Bloons would overrun the player before creating a full Boomerang setup.
