The Princess' Gown can only be equipped to female monkeys! (Black Void Shooter, Time Leaper, Bubble Gunner, Sword Monkey,... pretty much most of my monkeys). When equipped, said monkey's HP will go up by 30. Besides, she'll also gain the ability to heal herself by 2 HP every 3 seconds. Also, all the towers in her range will shoot 15% faster because of her royal influence.
