Pet dragon

I remember the first facebook application i used, it was called pet dragon. You started with an egg. You went on to hatch it and eventually train the dragon coming out of it. With it you beat other dragons and solve quests. You could either feed the dragon to enhance its weight (size), or train it to fight and increase its attack or collect gold to increase its money. The idea of this game was to make the dragon either big or aggressive or defensive. The best way to dominate was to enhance its strength after you have gained enough weight. Then beat up dragon dragons and steal their money.
