Smog the City Dog is worn out by the busy, buzzy city. All the bins on his street are empty and he's hungry. 'I'm out of here!' he says and scampers off across town to try his luck by the quiet canal. Sure enough, he spies ...dinner! But no sooner has Smog sauntered off with his tasty shopping, than Hedgehog, Fox, Cat, Mouse and Squirrel are hot on his heels. Just as Smog reaches top speed, the canal towpath suddenly turns a corner and Smog is left face to face with another dog. But Smog's fiercest bark is no match for his reflection and splash goes the shopping! Luckily, Mouse has a plan - with some teamwork everyone tucks in to a delicious soggy picnic!
