I'm amused by how you describe @little-ricky's behavior in the zoo; he's definitely enjoying his time.
Nice shot on the Giraffe taking its tongue out, it looks odd and it's really that long. I guess it needs every inch of it for grabbing the top-most part of the tree they munch on in the wild.
Chimps' behavior is always a funny one :D
Yeah I was kind of surprised when I saw it stick its tongue out. I have seen giraffes before, but I guess I never noticed them sticking their tongues out! Crazy.
And you did great capturing it at the right moment :)
