A former presenter for TV2's The Go Show, Jodie Bate is the producer, director and writer of the new 40-minute show, titled Charlie, Estelle and the Poppazoid Show.
Mrs Bate was encouraged by the early demand for the show, which will run next week at the Toitu Otago Settlers Museum.
The show was ''full of hip-hop, song and science''.
Youngsters could watch Charlie and Estelle as their unlikely friendship emerged ''through fun, wonder and laughter for the whole family'', Mrs Bate said.
Charlie saw the science and magic in everything.
Estelle dreamed of planets and stars, and ''an unlikely friendship emerges through invention, science, music and hip-hop dance''.
An Otago Museum spokesman said the six planned shows during the festival, by songwriter and performer Anthonie Tonnon, at the museum's planetarium had sold out.
The latest festival offered 230 events - up from 180 previously - and more than 30% of available seats were already sold.
The festival opens at the University of Otago's St David Lecture Theatre Complex on Friday evening.
The festival runs until July 15.
