An hour-long special. It centers on ReRun, Linus and Lucy's younger brother. It's Christmas vacation and, as usual, ReRun's big sister is stressing him out, so he decides to turn to his best friend, Snoopy, for amusement and holiday cheer. However, Snoopy has plans of his own, giving ReRun reason to ask Snoopy to invite his brother Spike for a visit. When Spike shows up, it looks like ReRun will have a dog for Christmas after all... but then the real trouble begins.
