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 huge animal of some type holding a blue flower. He is covered in red skin. He has 8 arms, 7 legs, 5 heads, 3 horns, and is shaking rapidly in the corner. He notices your gaze, and changes shape, just to amuse you.
