Mr. Men Little Miss, the iconic brand of children’s characters including Mr. Tickle and Little Miss Sunshine, has closed a deal to produce original TV series based on its catalogue.

Endeavor Content brokered the deal with Sanrio, the Japanese design and licensing company behind Hello Kitty. Announced on Wednesday, Endeavor Content stated that the agreement aligns with the company’s push to identify global intellectual property for family, young adult and kids content.

Created in 1971 by Roger Hargreaves, the charismatic lineup helps kids understand the world around them by illustrating specific emotions and personality traits as simple and colorful doodles.

Celebrating its 50th anniversary this year, Mr Men has sold more than 250 million times worldwide and Hello Kitty license holder Sanrio acquired the brand in 2011.

“We are thrilled to take the next step with our partner Sanrio and the Mr. Men Little Miss brands to help today’s children learn about their feelings, help empower them as they navigate the process of growing up, and to make them laugh along the way,” said Tamara Rothenberg, senior vice president of family, young adult and children’s programming at Endeavor Content.
