YouTuber Joseph Garrett, also known as Stampy Cat, and presenter Sara Cox have teamed up with American video game publisher Activision to find the UK's most imaginative child to become the Chief Imagination Officer for the game Skylanders.

Cox commented 'My son has always been a huge fan of Skylanders so I am very much looking forward to judging the UK's Chief Imagination Officer competition. It's great to be a part of an initiative that fuels creativity and I can’t wait to see the amazing Skylanders that will be dreamed up by the nation'.
