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 tiny animal of some type holding a pink beach ball. She is covered in red slime. She has 5 arms, 8 legs, 3 eyes, 5 horns, and is dancing excitedly in the corner. She notices your gaze, and changes shape, just to amuse you.
