This creature is you key to goof fortune, but you must be carful. Before you try to tame a Rex, Gaga, or other big creature (especially a moss) tame a bunch of fish. Any fish will do, but these are the best. Build a small base in the whiter with one submerged room full of your fish and a hole in the roof that you can only use from on top. Hatchframes are best but you can easily go without a roof if it’s high enough that nothing can escape. Still with me? Good. Next set all your fish on aggressive and begin praying to the great mosis-asaurus and asking him to his help. Next take your war prisoners, I know you have them, and if you don’t, get some. You need a minimum of three to feed to your fish in this order. First the lowest level, than the highest, than it didn’t matter. Take the meat from your fish once there done and use it to tame your beast. The creature will only tame if you made a good sacrifice, so the more sacrifices the better.
