Necromancer Monkey

The Necromancer Monkey is a special agent that can bring destroyed towers back as zombies. It costs $450 Monkey Money. Zombie towers keep all of the properties and upgrades they had before being destroyed, but cannot be upgraded and are only half as powerful as they originally were. They also have half as much health as they had started out with. After you've used the Necromancer Monkey in 50 rounds, it becomes the Necromancer Monkey Pro. The Necromancer Monkey Pro raise destroyed towers as well, but brings them back as ghosts instead of zombies. Ghost towers are still half as powerful as they were before being destroyed, but cannot be harmed.
