- The delightfully ominous Instrumental Theme Tune.
- Provided by Voltaire for Big Boogey Adventure. He even performed the music live behind the screen in some showings. He also did the Meteor's song, "Brains" in "Little Rock of Horrors".
- "Darkness" by SPF 1000, the song that plays during the Battle of the Bands episode. Everything from the presentation to the full song itself just screams Moment of Awesome.Cry! Cry! Everybody cry, because the world has gone awry! Darkness fills the sky and the reflections in your eyes!
- Scary-O is basically an awesome sea-shanty. With a shout-out to Slash and David Bowie in the middle.
- "Fear and Loathing in Endsville" gave us Like An Angry Woman. A parodic blues tune in which every adjective imaginable is described like an angry woman. Catchy and hilarious, thanks to Jim Cummings.
- "When monsters come to wreck your town, and you need heroes to rescue you, and the Super Friends just ain't around, then Underfist will rescue you!" Indisputably badass for a team dedicated to beating the hell out of supernatural threats. Pity it didn't get another special...
- In India the show is known as "Billy Mandy Aur Life Mein Haddi", and it got an absolutely rockin' new theme song to go with the name.
