What they do?Edit
Nothing much. All they do is work for their owner and be miserable until the day they die. Just children. They live and listen to their parents and teachers their whole life.
How to Have a Loyal Minion Edit
Minions also have feelings too. If you are an owner of a minion. Be kind to them so they will work harder, better and stronger for you. If you always yell at them, they will leave. And now you don't have any minion.
