[Space/Click for Next] The horns and eyes vary per individual. The Dolly Sheep reproduce by a process called "budding", where the spots on the sheep eventually grow big enough to pop off, and the these clumps of fur grow legs and faces and start running around.
Me, Chee, and Alien put our brains together for this. The horns are colored and shaped after DNA structures! Dino helped with the Ancient variant, that's why it's called that :)
