"Commander Peepers' Theme" is the leitmotif for Commander Peepers, usually heard in episodes centered on him. It is mostly instrumental save for a musical statement of Peepers' name.
- This theme makes appearances in:
- The Prisoner - Heard throughout the episode.
- The Bounty - A parody version is also heard during Peepers' daydream as "Janitor Pee-peeeerrrrrrss!"
- The Fancy Party - The first known appearance of the theme where Peepers is not the central character.
- The Day - The "Janitor Peepers" variation is heard instrumentally when Sylvia is being "carried away" by a sleepy Wander, disguised as a Watchdog.
- The Gift 2: The Giftening - The lyrics are not heard.
- The Funk - Heard instrumentally when Peepers blasts an insubordinate Watchdog and when Peepers yells at Hater.
- The Greater Hater - Heard when Peepers destroys Lord Dominator's control panel.
- The Big Day - Heard instrumentally when Peepers is about to destroy a planet.
- The Cool Guy - Peepers sings this while planning an invasion with Hater.
- The Battle Royale - Heard when Peepers and Sylvia join forces together, the lyrics was followed by "...and Sylvia!"
- Andy Bean admitted this is actually an adaptation of the Mexican folk song, "La Cucaracha".
