He looks like hes come right over to you for a quick pick. Must be Arthur. Hamlet is probably too old for standing up on his back legs. Are you bribing all of these animals to cooperate?
I rarely am lucky enough to see the wombats at all. I think in all my time going to the zoo Ive seen what is one of my favourite animals maybe a handful of times.
It's not too hard looking at a side profile here that if evolution stretched the little chap up and extended his rear legs and his muzzle and gave him a longer tail , he could be a kangaroo.
