Cadbury Advertisement

I find this ad rather creepy and cool at the same time. I did not really get what this ad have to do with Cadbury at first. I bet most of you don't think there's any relevance to the brand. Well, I guess because Cadbury is already so well known and everyone knows the main color for Cadbury is purple. The point of this advertisement is rather just to remind people of the brand by showing the color instead of focusing on the actual product.
