From Creatures Wikia
The Creatures 1 Jukebox plays one of two songs when activated by a creature or by the Hand. If the Cave Fly cob is injected, the jukebox will emit dancing chemical for your PMNs enjoyment. The jukebox was also successfully ported to Terra Nornia. A Music Change COB was also made by Mark Boehler, if you got sick of the music it played. A conversion has been made for Docking Station by Snapdragon.
