Never get attactched to your raptor if you use it to travel... I got attached to my twin mutation raptors but they died shortly after reaching adulthood to piranhas.1 like equals 1 respect for the twin raptors.
When my first raptor egg was incubating by my camp fire i sad "I hope i get twins with a color mutation."then the egg hatched twins and the had a color mutaition just as i withed for.
