Cereal Killer Soundtrack is an album released by comedymetal/punk group Green Jellÿ in 1993. It is the soundtrack to their video album, Cereal Killer. It was the first material the band released under the new name "Green Jellÿ" (as opposed to Green Jellö).
Cereal Killer Soundtrack was originally released under the band name of Green Jellö. However, as their fame grew with the release of the popular Three Little Pigs, the owner of the Jell-O trademark claimed that Green Jellÿ were violating their trademark, and forced a change of name. Because of this, an updated version of Cereal Killer Soundtrack was released bearing the Green Jellÿ name (also changing the name of the last track from "Green Jellö Theme Song" to "Green Jellÿ Theme Song") later in the same year.
The lyrics to the song Obey the Cowgod makes a reference to Beefcake the Mighty, bass player for the shock rock band GWAR, who taught Green Jelly how to make their latex costumes.
