Hmm, I love dolphins! They're my favorite H20 animal :) No, not just because they're the only other mammal, aside from humans, that have sex for pleasure (not just to reproduce) and engage in orgies. They're so peaceful, beautiful, friendly, and always look like they're smiling the way their lips curve up.
I wish the Garden had baby tigers though. Oh, and I'm pretty sad that Seigfried and Roy don't perform anymore, so I guess this is the next best thing :(
