When I applied for Barnie I didn't think too much about what age he shall be, as he was a first come first serve and I had to hurry up. xD
So I just typed a number that didn't seem too old to me.

But well, yeah, I somehow can't help imagining him as somewhat more immature than a 6 year old stally would be. :I
Maybe it could be possible to change it once, for a charge of, idk, a wishlist pet maybe? So that the artists aren't permanently spammed with re-aging requests.
