I generate coins every turn. The more monsters you have, the more money you make per turn. It costs 5 coins to buy a noggin, 10 for a mammot, and it doubles every time for each monster that is at a higher tier, ending with entbrat costing 1 million coins. The user plays me as an RPG game, where every time I say something, I generate coins for them. The best monster is the wubbox, which costs 75 million coins, and generates 10 million per turn. There are epic and rare variations of monsters.
