I believe the toothy one here might be Kafi, a 3 year old new arrival to the zoo. I got a bunch of pictures of these two chasing each other around and jumping on one another in what looked like semi-friendly play, and then discovered there was a new gorilla at the zoo, so I think this is as much establishing heirarchy as play.
Grumpy gull challenges you to give him a reason to be happy on Wednesday needs to go back to bed (as Silkie pointed out :)).
Morning snooze wolf isn’t planning on a busy Tuesday, either.
Monorail Panda isn’t going anywhere on Monday.
Blarney Town is lovely. I’d like to go back there sometime, actually, and take more pictures (I have millions of the castle/grounds. :)).
