Hmmmmmmm the eternal question that will never be answered. Plus I would love to know myself. But what about the other actors, mainly the little boy, who understood what Skippy was talking about. As far as I know they dont teach "Kangaroo" in the school system here.
I have never heard of a jaffa cake or biscuit you might want to ask another Aussie as I dont have a clue.
A Kangaroo is a native Australian animal so being an animal I find it strange that human actors can understand what Skippy was saying
The show was like Lassie you know when Lassie was barking and so on the other actors new what Lassie was saying quite funny really
STOP PRESS I just found out what a Jaffa cake and biscuit is. It is both. named after the Faffa orange. They both have a orange task about them. The biscuit is a thin waffer with a choc topping. Thats about all I know.
i think they might still teach kangaroo in schools here. my teacher made strange noises occasionally, that might explain it. although it doesn't explain why he kept asking what the time was and complaining that he would be late for a very important date
