Hypno K.K.

"Hypno K.K." is a K.K. Slider song that first appeared in after making an invalid song request. It was given an aircheck in as a secret song that can only be played by request. It is owned by Flurry and Papi.

The song is frequently regarded as unsettling due to its droning melody, high-pitched synthesizer whines, and use of reversed noises. This feature makes it popular in horror-themed Dream Towns like Aika Village. However, based on its original Japanese name, the tone of the song may have originally intended to be soothing or dream-like.
