Just completely submerge your egg in a glass or bowl of water, and wait. Within 12-24hrs, cracks will start to appear in the shell of the egg. And within 24 hours, you will have hatched your very own creature. Leave it in the water, and it will continue to grow! Once you take it out of the water though, after a few days it will start to shrink back down to its original size. Just put it back in the water, and it will start to grow again!
