SOMETHING's sound effect: Likely chosen due to the fact that if you listen closely, it sounds rather like the WHITE SPACE motif.

Not-So-Empty House: 0:39 - 0:46 is literally WHITE SPACE. How does nobody talk about this. WHY IS IT THERE.

Tee-Hee Time: 0:16 - 0:25, when the beat first drops and the battle starts, sounds incredibly similar to H20-HCL's first motif, the one that plays in the back of the whole song, which makes sense since they both play in Humphrey. Also, it shares a leitmotif with Sweet Paralysis and World's End Valentine, but I'm too lazy to timestamp it. Go listen for yourself.

PHOBIAS: While slowed, you can hear a bastardization of the WHITE SPACE theme at times, which I never noticed until 2 minutes ago and now I'm terrified.

Fleur: Built off of goddamn Lost At A Sleepover, which is frightening.

56-12-2: Same leitmotif as fucking Sugar Star Planetarium, fuck if I know why.
