Mojo is a little alien robot whose traveled millions of light years to gain knowledge of an endless universe.  Arriving on planet Earth, Mojo uses an info-beam collector ray to transmit research back to the home planet of Genegin.

 

Having been taken in by an adulting couple, who themselves are trying to figure out their own societal roles on Earth, Mojo learns of the many "hats" that humans wear.  Because of this, Mojo takes on different personas to fully experience the full human (and not so human) gamut.
