Rainbow is collaborating with the kids’ website CitizenKid to host four Winx Club treasure hunts at parks across France later this month.

Set to coincide with the country’s National Nature Day, the treasure hunts will challenge participants to solve a series of clues that will lead to a magical treasure trove full of Winx dolls and other goodies from licensees Hachette and Panini.

The treasure hunts will take place May 24 in the Jardin du Luxembourg in Paris, Parc Tête d'Or in Lyon, Parc Longchamps in Marseilles and Parc Bordelais in Bordeaux.

Rainbow teamed with CitizenKid last winter for a promotion that saw one fan win a Winx-themed trip to Italy.

“We are very excited to be extending our partnership with CitizenKid, especially as the last project was so successful in boosting brand engagement,” says Lorena Vaccari, head of retail and promotion, Rainbow Group. “Together we have put a lot of effort into a promotion that will bring the magic of Winx into the famous parks of France.”
