Mondo Sex Head is a remix album by Rob Zombie, containing remixes of the tracks of various past albums both by Zombie and his former band White Zombie.

Rob Zombie explained, "I never thought it would be a problem since it seemed tame to me... but it was.  No one would carry the CD.  Anything with death and violence is totally fine, but anything with sex, forget about it.  So instead of censoring that cover and ruining it, I just removed the ass shot and replaced it with a pussy shot."  Though the vinyl release remained unchanged with the original cover art.
