So I happened to breed two of these guys on accident. I have my little fella run around my base and both my dimorphs got stuck between my fridge and my AC unit. The animation for egg laying freed the Male and I spotted the red glow about a minute later. Even next to the ac unit the egg health was super low so I snatched it up and took it to my nursery. Out plopped this beautiful monochromatic female who I instantly fell in love with and imprinted on her. I named her silver and from then on she was always on my shoulder. From giga taming, to cave runs, to find the unicorn she's been my side. Feisty little thing too as she landed the final blow on an Alpha Carno bearing down on me. She got some prime meat for that!
