This turns out to be fitting, because the circus is a trap to kill Ken. Chargeman Ken!: "Waves of the Danube" in the Circus Episode is played in a minor key, and has a very melancholic tone.This track from the soundtrack of Paprika.The recurring number "Dream" from Mysterious Girlfriend X is definitely inspired by this.In Dragon Ball Z several of Majin Buu's themes in the Funimation score have circus motifs, which totally fits the childishly deranged and pretty unsettlingly nature of the Manchild Humanoid Abomination.A creepy little number called " Yuuenchi " plays in Cowboy Bebop when Spike Spiegel battles Mad Pierrot at his abandoned amusement park.Sadly the OVA downplays this scene a lot and the creepy circus music is rather bland. The ringmaster believes it's a "march from another world", that the gas is sentient and is communicating and directing all the infected circus artists, since they move along with its rhythm. There's also an orchestra of infected monster clowns that play an eerie tune, and the ringmaster points out that they aren't playing the instruments, but only blowing the virus gas into them which comes out as otherworldly music on its own.

Gyo: Towards the end of the story, the main character stumbles into a Circus of Fear where the insane ringmaster is directing a show performed by infected people and animals.
