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 really small animal of some type. He is covered in green leaves. He has 3 arms, 7 legs, 2 heads, 1 horn, and is sniffing nervously in the corner. He notices your gaze, and changes shape, just to amuse you.
