"The animated corpse of this monkey has returned from the grave to get revenge on its wrongdoers!" The Revenant Monkey is pretty different in comparison to most towers. First of all... it is not bought, kind of like the Monkey Hobo, except that you get this tower a different way. The Monkey Hobo will just kind of assert himself randomly after walking onto the screen. The Revenant Monkey has a 1% chance to appear when a monkey tower is killed.
