Kellogg's has unveiled a third ad in its Crunchy Nut series, this time seeing a group of alien spotters trying to keep quiet.
Created by Leo Burnett, the ad follows Snake and Dinosaur, with silence ruined as someone tucks into a bowl of cereal.
This time, it is Crunchy Nut granola that is being eaten in the latest 'The trouble is they taste too good' ad.
