The first animated production in the Peanuts series to be distributed by 20th Century Fox.

The first animated special in which Peppermint Patty acknowledges Snoopy is a dog and not a "funny-looking kid with a big nose." This running joke was previously concluded in the comic strip in 1974. In one strip, Patty apologized to "Chuck" for this confusion saying, "Let's just say my pride had the flu, Chuck."
