The Dairylea cows are back on the small screen from this weekend in a £1.2m ad campaign for Kraft Foods' new Dunkers Fromage Frais.

The ad shows the cows sneaking into a supermarket and placing the Dunkers in the yoghurt aisle before fleeing in a 'cow-mobile'. Their work is rewarded when a mum buys a tub, but things take a turn for the worse when the bovine adventurers lose control of their van and crash into a barrier.

"There is a great opportunity for this product to flourish," said channel and communications manager Sarah Petts.

Dairylea Dunkers Fromage Frais comes in strawberry and peach flavours with a side of digestive biscuits in single portions and packs of four.
