Pre-school animation The WotWots is now available on iTunes.
A free e-book download of the third episode of the TV series - Lanky Landing Legs - is the first to be launched.
Read by the series narrator, Martin Baynton, each word in the story is spelt out aloud, guiding young ones on pronunciation, while each page can become a black and white illustration allowing the user to colour it in.
"We are absolutely thrilled to be launching our very first e-book for free via iTunes," said Richard Taylor, co-founder of Weta Workshop. "The series prides itself on being entertaining and fun for kids and offering an element of early education, so the e-book is a great way for our fans to enjoy these components and interact with the WotWots."
