After being given to a little boy for Christmas from Santa, a very excited and happy robot named Robie Junior goes to work immediately playing with the little boy and guarding his toys. At first, they are inseparable, playing during the day and cuddling up to sleep at night. Eventually, the newness wears off, and Robie Junior finds himself alone most of the time. Robie Junior's heart is broken, but nonetheless, he continues to stay in the little boy's room guarding all his toys.
