I don't know the official name of the song but it plays when these guys show up.
This OST on YouTube is scattered all over the place; for all I know this song may have already been put up but I couldn't find it myself.

NOTE: this isnt the song from Glitchland.
Glitchland is silent but I messed around more with other games and this song came up.
Not as good as hCII0vERKiLL`s scary sonic song
but still very unsettling
