Look at the creatures.

Serris was interested in the various things she saw on display. She first neared a few low cages. First she saw what looked like some odd-shaped fuzzy lumps with black beads dotted in odd places. Looking the other way she squirming pile of shiny clack creatures.

A large creature in a cage watched her as she wandered about the exhibits. It looked a mix between a tiger and a dragon. It's snout prodded the bars. While she was looking back, she felt something prod her bottom. When she turned to look, the creature appeared to be a hairless mix between a goat and a deer. It's skin was a greenish brown color, and it's horns forked a few times. Serris cautiously reached toward it, and was able to pet it between the base of it's horns.

It seemed to be safe enough wandering around, until she noticed some things that weren't there. Near a glass tube that had some familiar-looking fish together, there was another broken cylinder. There was some slimy pink residue in the tube, and a number of matching trails on the floor. And somewhere else she spotted an empty cage with bent bars.

Evidently, not everything that was supposed to be here was well-contained. The escaped exhibits could arguably be anywhere, but odds were better they were still nearby.
