Put the Growing Pet Dinosaur Egg in a container filled with enough water to cover it. The water temperature must be less than 35C. The egg shell will slowly break after 12-24 hours and your dinosaur will emerge. Be sure to keep the container full of water. The egg shell will break. Once the egg shell is broken entirely, then you should add fresh water to the container. Your dinosaur will continue expanding for 24-48 hours. After 48 hours, you might like to move your dinosaur to a larger container and watch it grow daily.
