Almost feel sorry for Atlas, I think it might have a mutation that caused it to grow much bigger quickly than a regular fluffy seeing as it didn't seem that bothered with beating up a smarty but is worried it could possibly hurt its mother and (I think) the rest of its infant siblings.
I used to have smarty, born by a *beautiful* alicorn, but, i used it for aiming practice, he deserved it, he would do stuff like hit “mummah” and try to bite his other siblings, he was also a beautiful earth stallion, he was SOOOO annoying dude
