Independent creative agency Studio Liddell has licensed Chapman's Fifi and the Flowertots and Roary the Racing Car brands, with plans to launch an iPhone app and develop games for the Nintendo Wii.
The company has worked with Chapman since 2004 to produce the CGI content for both TV shows.
The Roary iPhone app - Rollin' Road - is due for release imminently, with the game using the iPhone's accelerometer functions to control Roary.
In addition, Studio Liddell is also developing Nintendo Wii games for the two properties, expected during 2011.
"Roary and Fifi are fantastic properties with huge potential for multi-platform," said Ian Liddell, MD of Studio Liddell. "We have been working hard to develop games that will make kids feel they are fully immersed in a real-life episode of Roary or Fifi, and we are currently speaking to publishers to launch the Wii games early next year."
Valerie Fry, director of licensing at Chapman, added: "The team at Studio Liddell are experts in animation and interactive applications, and therefore we are very pleased to be working with them again on Fifi and Roary in this capacity."
