The Cloning Bloon cannot be defeated. If it is attacked, it creates a clone of itself (resulting in two Cloning Bloons). This can become a big problem quickly if your towers keep attacking them. The only way to survive when a Cloning Bloon comes is to make your towers stop attacking temporarily by using Cease fire! or by selling all your towers. If this bloon escapes, it causes you to lose 1 life (so you will always lose at least 1 life when it comes).
