Chapman Entertainment is teaming up with giant toy store Hamleys during its Cartoon Crazy Month, hosting a Fifi and Roary Week in March.
As part of the week - running from March 23rd to 29th - Chapman will be providing character visits throughout the weekend from Fifi Forget-Me-Not, Big Chris and Roary the Racing Car.
Fifi and Roary branded balloons and stickers will be handed out to children, while there will be giveaways in-store including a competition to win a range of products.
Melissa Brown, director of marketing at Chapman, commented: "The Cartoon Crazy Month provides a great opportunity to drive further awareness around our popular pre-school series. We are combining both brands together to offer a girls and boys proposition.
"We are confident that Fifi and Roary will be a big pull for pre-schoolers based in and around London, as well as for international tourists on holiday, who are familiar with the brands from their home country."
Hamleys will be supporting the initiatives by printing 20,000 leaflets, 5,000 tray liners and 20 overall themed posters throughout the month.
Matt Webb, head of marketing at Hamleys, said: "We are really excited about our Cartoon Crazy promotion. Animated properties are such a major part of our product offering, with Fifi and Roary integral to our pre-school range."
