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, Jeremiah, Papi, and Sherb.

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. This is reflected by the English name — "hypno-" as a prefix relates to sleep — as well as how Sherb, a sleep-themed Lazy goat, plays it in his house.
