Aardman Animations' orange, green and pink clay people are taking on new roles in a government campaign to expose the "hidden nasties" in everyday food.
Steve Harding-Hill, director of the Change4Life project at Aardman Aninations, says this project is very different to the advertisements he normally works on:
"This feels special... We are not just creating animation for animation's sake."
