Unseen characters

• Adults implied in the strip include: all of the characters' parents; Linus van Pelt's teacher Miss Othmar; Miss Halverson ; Charlie Brown's baseball hero Joe Shlabotnik; and Linus's blanket-hating grandmother. Adults in most of the Peanuts animated cartoons are only heard by the unintelligible sounds of a trombone.
• The Little Red-Haired Girl, seen in many animated television specials where she was known as "Heather", but was never seen in the strip itself.
• The Great Pumpkin, a holiday figure whom Linus believes to appear in the most sincere pumpkin patch to deliver presents to good children, but never confirmed to be real and is likely a legendary creation of Linus's imagination.
• The Cat Next Door who often destroys Snoopy's house.
• The Red Baron, is the nemesis Snoopy fights while in the guise of a World War I Flying Ace complete with goggles, helmet and scarf. The battles occur while Snoopy is perched on his doghouse that becomes his Sopwith Camel plane through the power of his imagination. The battles between Snoopy and the Red Baron began in an October 10, 1965 Peanuts strip.
