There are two versions of the 6th stage. In the Japanese and PAL versions of the game, the stage takes place in hell. In the American version, the stage instead takes place on a volcanic island. Both stages have different graphics for Lammy, a different intro cutscene, and a slight change in lyrics in the first stage to remove any references to hell or the devil. The Japan-exclusive Um Jammer Lammy NOW! retains the island plot from the US release.
