Howler Monkey

The Howler Monkey is a special agent that costs $110 Monkey Money and that howls very loudly. Its howls travel in a straight, focused line, until they hit bloons. So much shaking is caused by the sound waves that bloon layers keep popping as long as they are within the blast of sound. The Howler Monkey can only be used if you have a Microphone - it keeps howling as long as you scream, shout, or make other loud sounds into the microphone. If you use the Howler Monkey in 50 games, it becomes the Howler Monkey Pro. Instead of being in a focused line, the Howler Monkey Pro's howls create shockwaves that pop any bloons within a certain distance of it.
