Here's another of Meatball and there below is Genevieve with Justin Long. Somehow, she seems to have grown an extra paw, one that is moving south near Justin's nearly exposed privates.

One of the neatest things were these water creatures, upside-down jellyfish. They were projected individually on a screen in front of the tank. To put it plainly, it was beautiful.
