(On a side note, I know exactly what Abby's bunny would look like. There were these bunnies at the pet store near my house that were white with black around their eyes (eyeliner) black ears (the pigtails) and black feet (the boots). Obviously Abby in a bunny form)
I think that Spock's would be himself. Because he's that awesome.
Ok, since we've done Abby, what would Gibb's patronous be?
