What the picture shows

A pink, hairless, mole-rat-like creature with a wide open mouth showing two large yellow buck teeth, one arm raised in a waving gesture, rendered in a low-poly 3D style against a white background. Chatters likely use it as a cheerful, goofy greeting or wave to welcome someone into the stream.
