When Cooper's girlfriend Amber is transformed into a disgusting mutant, Crivens helps Cooper turn her back into her normal self. Just before the final battle with Baron von Ghoul, Crivens seemingly beats up the Baron and walks towards Cooper with the skeleton key necessary to free all the imprisoned children. However, Crivens smacks Cooper with the key and reveals himself to be none other than Baron von Ghoul in disguise.
