There are three islands filled with dinosaurs but all of them want to eat you. So to tame one, you must return the favor. To tame any creature on the ark, it takes 100 eggs specific to the creature you want to tame. There are at least three ways to get eggs. The first is to watch a random video, each will give you 1 random egg, some gold, and a couple of any type of resource. The other is to get crystal eggs. These can be bought with outside money and can be found in clutches of 1-5 in eggeries hidden around the island. Each crystal egg will give you 5 eggs from any creature including rares like the megalodon and dragons. The other and more common way is to kill one of the creatures you wish to tame.Each drop will include at least 1 egg from that creature and can include up to twenty.
