Snoopy's Reunion DVD features two tv Peanuts specials, Snoopy's Reunion and It's Flashbeagle, Charlie Brown as well as a featurette.
Snoopy's Reunion features Snoopy, after feeling depressed, deciding to reunite with his siblings at the Daisy Hill Puppy Farm. They, along with Charlie Brown and Sally, end up at a parking lot that now occupies where the farm was and the beagles play their musical instruments anyway.
It's Flashbeagle, Charlie Brown features Snoopy and the rest of the Peanuts gang getting involved in physical fitness and dancing.
A featurette called Together Again: A Peanuts Voice-Over Cast Reunion features the actors, who provided the voices for the Peanuts characters, at ComicCon 2008.
