The Peanuts gang returns in I Want a Dog for Christmas, Charlie Brown. The story concerns the younger brother of Linus and Lucy Van Pelt, Rerun. Rerun wants nothing more than his very own dog, but his parents are unwilling to get him one. Unable to convince Charlie Brown to lower his ten-million-dollar asking price for Snoopy, Rerun decides to adopt Snoopy's brother, Spike, who has come to celebrate the holiday season.
