A visit to Jungleland Safari Park reveals the rumor that a werewolf (who is decidedly not Fangface) has been abducting animals for unknown purposes. The gang encounters the werewolf on the safari path, and they pursue him in an attempt to discover his secrets (while Fangface hopes to be reunited with a lost cousin). Unfortunately, the crooked werewolf escapes, leaving Fangface to be pegged as the culprit by the park authorities. The villainous werewolf reveals himself to his animal prisoners as the park's own caretaker Zoloff, who has created a serum that can mutate his DNA. In his human form, he has no problem letting Fangface take the fall for his own deeds, and the gang has to find a way to prove Fangface's innocence.
