Snoopy's Reunion (1991)

Snoopy's Reunion is the 34th prime-time animated TV special based upon the comic strip Peanuts, by Charles M. Schulz. It originally aired on the CBS network on May 1, 1991 as part of the animated anthology series Toon Nite. It is the only Peanuts TV special to date (and the only animation other than Snoopy, Come Home) not to have "Charlie Brown" in the title (though the working title was Those Were the Days, Charlie Brown), it is also one of the few Peanuts specials to feature adults on-screen.

Storyline
To cheer up Snoopy, Charlie Brown helps him organise a family reunion of his litter siblings.
