The five versions develop the "obviously another Crunchy Nut" campaign by showing how far people will go to eat the cereal.
Each ad is of a familiar food that has been adapted in some way to include Crunchy Nut Cornflakes.
In "cocktail" the drink in a cocktail glass is replaced with milk and, instead of an olive, the drink is accompanied by a Crunchy Nut Cornflake.
Similarly, in "lollipop" the usual ingredients are substituted for milk and Crunchy Nut Cornflakes, while in "sandwich" two Crunchy Nut bars are positioned on top of each other with a lettuce leaf in between.
The ads were written and art directed by Matt Collier and Wayne Robinson. Photography was by Jenny Van Sommers.
The media activity, which was planned and bought by MindShare, will focus on Metro. The ads will run in the London-based free paper for five months.
