The Monkey: This is the ultimate tower you can build, just like The Bloon is the ultimate boss. You can only build ONE of this tower. The unique aspect of this tower is that you can control it YOURSELF. When you select it, you can see a targeting sign similar to the Mortar Tower, and where you click, The Monkey will shoot at that place; this tower has infinite range. The splash area of this tower is extremely large, almost as large as the Super Monkey’s Super Range; and it has almost instantaneous reload speed. Initially, the shots of The Monkey will bring down volleys of darts and bombs. Level 2: The volleys of shots fired by this tower will now include ice balls, poison bombs and corrosive glue splatter. Level 3: The volleys of shots fired by this tower will now include special attacks such as tempest tornado, electricity, gravity, and multi-layer-stripping attacks. Level 4: The darts and bombs shot by this tower will be replaced by energy attacks such as laser, plasma, and sun ray. Level 5: Every 5 seconds, all non-boss bloons inside the splash radius of this tower will be wiped out. This is similar to a localized Monkey Storm, and is the most powerful and expensive ability in game.
