Primary pupils could soon make their own contribution to the iconic Mr Men series while also raising money for charity.
Children with Cancer UK wants them to design a new character and write a new story for the series.
Younger students aged three to six can also take part in a colouring-in challenge.
The sponsored entries will be pored over by the Mr Men designers and Children Cancer UK team, and the winners will be “brought to life” and featured in the Mr Men Little Miss magazine.
Cliff O’Gorman, chief executive of Children with Cancer UK, says: “Mr Tickle, Little Miss Sunshine, and Mr Bump have been a part of so many people’s childhoods, and it is exciting to be able to give a new generation the opportunity to create an inspiring character.
“By taking part in our Mr Men and Little Miss challenges, pupils, parents and teachers can help children today and in the future.”
The deadline is August 31 and the winners will be announced on September 15.
