Someone at McVitie's decided it was time to break their iconic Penguin biscuits down into their constituent parts - caramel, chocolate, biscuits, tiny little lumps of delicious happiness in a tube. This new confectionary revolution was to be called Penguin Chukkas. How to sell them? Well, if you ask me, it's obviously by convincing kids that tiny Penguins lived in their heads and controlled their emotions. The only way to get the penguins to click the 'happy' switch was to show them a packet of Chukkas.
