A&B TV and Bulldog Licensing have inked a deal with Box of Frogs Media to produce a series of interactive app books based on the animated duo Roobarb and Custard.

Box of Frogs is planning three new app books that bring together original script from the brand's 1970s cartoon, animations and interactive narratives. The first book will launch in October to help celebrate Roobarb and Custard’s 40th anniversary this year.
