Ping-Pong Monkey

The Ping-Pong Monkey is a special agent in the next Bloons Tower Defense game, and costs $100 Monkey Money. After you place it, it hits a ping-pong ball straight up, causing one layer to pop off any bloons that it hits (with the exception of lead bloons, which it can't damage, and MOAB-class bloons and bosses, which it does one damage to). The ball then falls back down, again causing one layer to pop of any bloons that it hits. After you use the Ping-Pong Monkey in 40 games, it becomes the Ping-Pong Monkeys. When you buy this, you get two Ping-Pong Monkeys that you can place anywhere (but that must be within a certain distance of each other), and that hit a ping-pong ball back and forth rather than straight up.
