Starsky is a demonic Gerbil that appears in the Season 7 episode, "Monster." When he first appears, he is shown to have brown fur, small ears, a tiny nose, and black eyes. He then quickly transforms into a hellish looking creature, now having large wings, red horns, sharp claws, a pointed tail, glowing yellow eyes with dark bags, and red fur. 

After he jumps out of Meatwad's closet and changes into his possessed form, he begins to spew vomit from his mouth and spin his head around. He then jumps into the arms of Frylock, who says to the Gerbil, "Come into him, damn you! Come into him!" directing his eyes at Shake. Starsky's demon then possesses Shake, morphing him into a horrifying creature as well.
