Octonauts Lighting Technical Director Paul Sheehy has a secret weapon - not only does he oversee and direct the other lighters and help make the shows look as good as possible in the time available - but Paul's cousins' son Jack (aged 4) is an Octonauts fanatic.

“Every time he comes over to the house he goes off on these rambles about Octonauts. He is absolutely NUTS about the show and comes to see me just to talk about Octonauts! Jack gets so excited talking about it that he trips himself up talking while telling me about it. He knows more about it than I do.”
