Final 'Peanuts' special produced and directed by Bill Melendez, and also the final performance by Melendez as Snoopy and Woodstock, respectively. He would appear posthumously in The Peanuts Movie (2015) through use of archived audio.
This special was the first and only time a CGI shot was used in a Peanuts special. Specifically, the shot of the bus pulling into the camp.
The storyline is based on two different series of strips. The main plot involving the Joe Agate character originally appeared in April 1995, while the subplot of Peppermint Patty sneaking into camp to see "Chuck" was from 1989.
This special originated as "It's Only Marbles, Charlie Brown" and was the last special to have involvement with Charles M. Schulz before his death. Schulz had already retired from writing the comic strip when he was working on the special, and as he wrote it, he said to himself, "I just realized that Charlie Brown is never going to kick that football. Good grief."
