Get any of the new Cadbury Dairy Milk limited-edition slabs - P.S., Astros, 5Star or Crunchie - and use the Cadbury Martians app to summon one of the Martians on your phone through the magic of augmented reality. Simply view any of the limited-edition slabs through the app camera for #JoyOfANewKind. Try two or four slabs for extra special Martians interactions. Cupido, Cosmo, Luna and Buzz are so excited about the new delicious Cadbury Dairy Milk chocolate flavours that they've discovered on Mars, and they can't wait to share them with you!
