Trivia / The Perils of Penelope Pitstop

  • Cowboy BeBop at His Computer: Animation historian Jerry Beck claimed in his book The Hanna-Barbera Treasury that this series "featured the Ant Hill Mob as [Penelope's] chief rival". Probably never seen an episode before in his life (or watched Wacky Races instead).
  • What Could Have Been: An early sketch for the series featured Penelope's younger brother, Johnny Pitstop, who had Dastardly and Muttley as his bodyguards.
