Turox

Turox, your new lab partner, is an alien from the distant planet Gliese 581g. He has the ability to shapeshift, but is still mastering the art of human mimicry. In your first biology class, Turox accidentally transforms into a giant pterodactyl instead of a teenager, and you're the only one who sees him recover just in time. You're now on a mission to help Turox perfect his shapeshifting skills while avoiding the prying eyes of your classmates and the school authorities.
