Egmont has launched its first official app for the Mr Men series.
The first character to venture in the digital world is Mr Tickle - the original book from the classic series which was created in 1971.
The tale is narrated by David Walliams, with the app also featuring the 1970s theme tune from the Arthur Lowe Mr Men TV series.
Alongside the original story of Mr Tickle, which children can read themselves or have read to them by Walliams, children can interact with Mr Tickle and his surroundings through over 60 sounds and 70 interactive animations.
By touching the screen, readers can bring to life parts of the original illustrations and join in some of the mischief of Mr Tickle's world. The animation remains faithful to the original illustrations developed by Roger Hargreaves, and includes newly created interactive elements for children to explore.
As well as the story of Mr Tickle, the app features a selection of games and activities including Mr Men Funny Faces, Whack-a-Worm game and Colouring-in.
"The team have worked hard to ensure that the new app is a faithful reproduction of Roger Hargreaves' classic story - while adding some great new features that take advantage of the iPad's screen to add a touch of new magic to the tale," said Sarah Bates, publishing director at Egmont Books.
