Under the supervision of his new human parents, Bob (Pat Finn) and Liz (Mim Drew), Marvin tries to adjust to life on Earth as a typical American teenager.

Helping him navigate Earth's unfamiliar social customs are Marvin's human siblings Teri (Victory Van Tuyl) and Henry (Jacob Bertrand) and his mischievous grandfather, Pop-Pop (Casey Sander).

As if teaching Marvin how to act human was not hard enough, the family and even Teri's curious best friend, Briana (Camille Spirlin), must also conceal his real identity from the world.

The series originally aired on Nickelodeon in the United States on November 24, 2012, and on YTV in Canada on March 19, 2013.
