The Bunyip Babes are so great in number, and so very mischievous, that their father goes to sleep for a year at a time and leaves their mother, 'Mummybun', to look after them all. Nulla and Tilba, the naughtiest of all the Babes, have many adventures in the bush with their siblings and meet mythical creatures and Australian animals, all the while trying to avoid Mummybun's discipline.
