While "Scandinavian Leather" was recorded at their own Crystal Canyon Studio in Oslo, Turbonegro decided to bring in Steven Shane McDonald as co-producer for "Party Animals". This follow-up to 2003s "Scandinavian Leather" and the last installment in the Apocalypse trilogy was released throughout Europe on 9 May (in Norway 2 May). It continued the 1970s and 1980s glam metal and hard rock-influenced party-oriented deathpunk sound that was first introduced on "Apocalypse Dudes". "Party Animals" was followed by intense touring throughout Europe and, in October, they visited the U.S. A collection of remixes and rarities appeared in 2005 as "Small Feces".
