Here's my entry for the cool category, Rygel:
He's a pet store Veiltail who loves his food and bites his tail whenever someone so much as touches his decor. But he also wiggles very happily whenever I walk into the room. When we got him, nothing would make him flare. It took him a month to flare at anything, but now he flares at the back wall of his tank whenever I do a water change. He seems fascinated by my phone and camera but rarely sits still for a photo.
