Both Creatures 2 and Creatures 3 have a sound file called "DJ_G.wav" which can be found inside the "sounds" folder, these two tracks are different and features the top-class, greenback DJ himself remixing some vibes with Norns for percussion. No creatures were harmed in the making of these tracks.
There was an intention to make a new one for Docking Station, but being a download-only game it seemed a bit much to increase the download size with an easter egg.

The tracks will be made web-ready and accessible here at some point in the future.
