When you use an idol, a Oobaboo Chief will face you and trade you for the idol.
The Oobaboo Chief will then offer one of three of his tribesman to assist you. You may pick from a warrior, a healer and a gatherer. The warrior will follow you around guarding you much like your robot does. The healer will follow you and heal you when your health becomes low. The gatherer roams the land and gathers anything in sight, giving it you you as he gathers.
Please note you may only have 1 Oobaboo tribesman working for you at any given time.
They work for a short while before disapearing.
