Empathy Bloon

The Empathy Bloon spawns at the beginning of the path and moves as fast as a yellow bloon. It takes 10 hits to defeat, and might seem to have no special powers at first. However, any tower that damages it is also damaged by the same amount. Therefore, destroying it will cause your towers to take a total of 10 damage (which may be spread among multiple towers). If it escapes, you lose 20 lives.
