Six rules. That's all. Good luck. 1. Must be on the medium or hard snow island 2. No breeding 3. No fighting anything that can hurt you. Fight or flight: Always flight 4. No heat bodies. If an animal has a heat body you have to banish it, but recessive is OK 5. No messing with any sandbox setting except making sure your animals don't have heat bodies and selecting your island. 6. No eating anything but meat. You can break berry bushes, but not collect from them.
