This show marks the only time Peppermint Patty says "Charlie Brown" rather than "Chuck".
Charles M. Schulz considered the arm-wrestling scene between Snoopy and Lucy the best-animated scene of all the Peanuts specials.
This is the last special where Peter Robbins voiced Charlie Brown.
When Snoopy pretends to be a bus driver, he passes by a map with references to several members of the crew, including Schulz City (for Charles M. Schulz), Levittown (for Ed Levitt, one of the animators), Gruyerberg (for Bernard Gruver, spelled wrong, another one of the animators), Leesville (for Lee Mendelson, executive producer), and Cuidad (another spelling error) de Melendez (for Bill Melendez, executive producer, director, and voice of Snoopy).
On April 20, 2024, a full soundtrack album containing the remastered original recordings for the special and several bonus tracks was released for the first time in honor of the special's 55th anniversary.
