Monkey Mercenary

The Monkey Mercenary is a tower in the next Bloons Tower Defense game. Instead of upgrades, it gets weapons from the Weapons Shop, but many of its weapons are different from those used by the Monkey Warrior. Its weapons are also fairly cheap, but there is a catch to using this tower. You must pay it some amount of money every round, or else it will leave (disappearing as though it has been sold, but you won't get any money). The amount of money you must pay it will depend on the difficulty of the round (more difficult rounds are harder "jobs" for it, so it charges you more money).
