Guest Stars Edit
- Episode 01: Pecos Bill Cleans Up the West, Episode 14: Lionel's Great Escape Trick, Episode 15: There's a Fly in My Soup, and Episode 30: Be Bop featureed two The Vowelles segments, instead of one. This incident stopped at Season 2 replaced with a silver tinsel background.
- Episode 05: Shooting Stars and Episode 07: Touching the Moon were the first episodes to have library scenes in the middle where a character makes up a story and turns it into a song, as a result, The Vowelles weren't featured in those first two episodes, this incident continues in Season 2, in episodes such as Episode 32: Humph! Humph! Humph!.
- This is the only season to be produced with a total number of 30 episodes.
