I thought my 2 1/2 year old should have an Ancestor of his very own. It came out a little *too* cute and my toddler seems to think it should moo, but someday I hope he'll appreciate it properly. I plan to make a few more that will hopefully be a little less bovine in their cuteness. Thought I'd share it here, though. I hope this pastes ok, I've also included links to my Flikr.
