A tower defense game series made by ninja kiwi that involves monkeys defending a level destroying bloons before they reach the end. While the towers are usually focused on monkeys there are other towers such as the tack shooter, bomb shooter, spike factory, or banana farm that don't. The bloons you need to defend against will come in multiple layers, special defenses, and even blimps (M.O.A.B. class bloons) that can end a run if they reach the end (ex: Massive Ornary Air Blimp (MOAB), Brutal Floating Behemoth (BFB), Zeppelin Of Mighty Gargantuaness (ZOMG), Dark Dirigible Titan (DDT)) and have higher health than regular bloons.
