Bixby the animal

This is Linda's pet. You can't quite tell what it is, as its shape seems to be in a constant state of flux. A small animal of some type holding a yellow towel. He is covered in yellow slime. He has 2 arms, 1 leg, 5 eyes, 5 horns, and is sniffing quietly in the corner. He notices your gaze, and changes shape, just to amuse you.
