still working on the lore but right now i'm working on the biology and why they 're the way they're are

-they're born from galaxy patterned eggs that have grey shells with a dark galaxy dripping pattern on them - the dark galaxy pattern foretells what the back markings on the babies will be - they babies are rarely born without a twin - as soon as the hatchling reach a week old their galaxy patterns fade and stripes appear - as the hatchlings age they get more stripes and more colors in the stripes - at 6 years old the young creature starts to get it's antlers

please critique this so far but i think this is pretty original but idk ^^ (attached anim is an example of an adult)
