Trivia

• Some of the storyboards for this episode were posted on Flying Iguana Animation's YouTube channel on 2 September 2024.^[1]
• Several differences between the storyboard and final versions of the episode occur:
  • Diesel pulls a construction flatbed during the song.
  • Kana whooshes Diesel's headphones away directly after the song.
  • Diesel has a built-in winch to pull the culvert cover out instead of using a rope from his flatbed.
• According to the Australian Google Play plot description, Carly and Sandy were originally supposed to help Percy get the ducklings out of the culvert, but were later dropped for unknown reasons.^[2]
• This episode was the last episode to feature The Mainland.
