Milk lives in the grubby seaside town of Slopp-on-Sea - a rubbish name for a rubbish town. But Milk;s life is pretty rubbish too, so it fits. She and her Granddad get on OK, but nowadays he;s always wandering off somewhere, or asking her befuddled questions. But then one day, he comes back from one of his jaunts with a recipe book in his hand: THE PORRIDGE OF KNOWLEDGE.
Intrigued, Milk enlists the help of her friend Carp to try the recipe. At first it looks like all they;ve managed to create is a lump of malodorous goo - but then they notice the ants (who have been nibbling the porridge) building a mashed potato replica of the leaning tower of Pisa... So they decide to try it out on themselves. And the results are incredible! Suddenly Milk and Carp are the cleverest people in town - and Granddad is back to his normal self. But are Milk and Carp about to discover that sometimes a little bit of knowledge goes a long way...?
