Cat's Eye Marble
Tux, a long mysterious noodly mammal of some sort with magpie wings, six paws, and a mossy green sheen to its coat.  They slink over a hollow log in a dimly-lit forest, doing a double-take as a velvet worm with scruffy hair and glasses crawls out to see what's making all that noise on its roof.

Tux (mossy coat) (and Worm/Theo), for TuxedoDragon.  Description from Art Fight:

Noodle encounter....

Nearly halfway through Art Fight and I finally get an attack up.....  Went way harder on this than I intended going in hahah.  I'm on Team Crystals this year!
