Bob's can-do crew is busy decorating for the holidays and building a concert stage for rock stars Lennie and the Lazers. And guess who's coming home for Christmas? Bob's twin brother, Tom - all the way from the Arctic Circle! Unfortunately, things don't go as planned. Spud is up to his usual pranks, Lennie can't sing, and Bob forgot his Santa costume. And it seems Tom won't be home after all. Much to Bob's surprise, Elton John and a mysterious Santa make it a special Christmas to remember!
