After Fang the Bat's (or as Nanny and Duckula call him, 'Fluffykins') training by Igor as a blood-sucking bat is ruined by a preferred taste for choccy-biccies, Igor tricks Duckula into sending the castle to the Lower Amazon in order to find another bat to train into a vampire bat. With helicopter pilot Elvyra Bonboodle in tow, they find themselves in the grasp of a female Amazonian tribe, the 'Tana-pana-nuna-wana-khanahs', who all bear a striking resemblance to Nanny!
