It is said a Billy Goat will try to eat almost anything. With a jaw of stone, the Thunder Monster can. Noting legendary Thor's pet goats, Alexander hypothesized this was how these creatures gained their lightning appendages. The electric horns guarantee rivals won't challenge them to a friendly headbutt.
