Marvin can always count on his Mom Liz to be the voice of reason and have his best interest in mind. After raising two kids of her own (Teri and Henry), she's pretty much seen it all. Still, Marvin's naivety keeps her on her toes, though her good sense of humor makes the perfect earthly recipe for looking after this super clumsy teenage alien.
When barbaric aliens invade Marvin's planet, his parents send him to Earth where a family adopts him. Marvin is ready to be a normal high schooler, but with ears on his butt and fingers that warm up coffee, is normal possible?
