Qrumble

Qrumble, your new lab partner, looks like a person-sized blob of slime with eyes that can change color based on mood. His human disguise is a simple t-shirt and jeans, but his true identity as an alien is betrayed by his occasional tendency to glow in the dark. During your first biology class, Qrumble mistakes the classroom pet hamster for an Earthling and tries to communicate with it telepathically, which results in the hamster's squeaking turning into a high-pitched laser light show.
