J Walter Thompson has given a new twist to its ‘kids will do anything’ campaign for Kraft Jacobs Suchard’s Dairylea brand. To make the brand more appealing to children, a new ad shows how a gang of mice will do anything for Dairylea. The ad features claymation mice, led by their hero Dexter, who raid a fridge full of Dairylea and overcome their arch enemy, Fat Boy the cat. The ad will run nationally for four weeks with a media spend of 3m. It is expected that it will be shown a second time later in the year.
