For over 50 years it was a staple for Kiwi kids - be it in book, radio play or theatre form: Spike Milligan's Bad Jelly the Witch.
Originally a short handwritten story for his kids, it was printed in 1973 and made into an audio version.
It was phenomenally popular here - in fact it was the most-licensed New Zealand play and believed to have over one hundred productions throughout the country.
But it's set to get a new generation of young fans thanks to Mukpuddy animation studio who have picked up the rights and have turned it into a 13-part series with British star Miriam Margolyes as Bad Jelly.
Ryan Cooper is one of the co-founders of Mukpuddy, he's the co-director of the new series (streaming now on TVNZ+) and also the author of a new book, Badjelly, that's just been released.
He joins Kathryn to talk about how the book and series came about and the perennial popularity of this deliciously pernicious witch.
