Boomerang Monkey (BTDU)

"'Throws a boomerang in an arc back round to the monkey. Good range and pierce, but less predictable.”"One of the classic BTD towers, Boomerang Monkeys are well equipped to deal with waves of weaker bloons, but also have a few upgrades that make them viable against heavier bloon types and even M.O.A.Bs.

The player is able to unlock Boomerang Monkeys as soon as Level 2 and is guaranteed to have them by Level 9, as their primary typing makes them one of the 8 possible picks at that level range.
