The week-long “PJ Masks” activity-based campaign will promote healthy living and encourage physical activity in Tumble Tots classes across the U.K. in February. As part of Healthy Heroes Week, which launches on Feb. 4, children (ages 7 and younger) will participate in activities that will strengthen their physical, social and cognitive skills.

Each class will be supervised by specially trained staff and offer programs according to the child’s age and stage of development.

“The newly formed partnership with Tumble Tots is a great fit for ‘PJ Masks,’ and we’re delighted the show’s popularity can be channeled into this positive initiative,” says Rebecca Harvey, executive vice president, global brand management, family and brands, eOne. “We have worked closely with Tumble Tots to create an activity program that will be both fun and interesting for young children who aspire to be healthy and active like their favorite characters Catboy, Owlette and Gekko!”
