Lez and Dez, the Slugs, want to get their own back on Gordon for never letting them eat the gardens’ plants. When Gordon’s not looking they sneak under his hat and repeat a magic growth spell they have just overheard Gordon use. Lez and Dez are soon ordering Gordon to give them food and because they are bigger than him, he can’t refuse. But when Gordon finds out how the Slugs became large he tricks them into believing that they have eaten all the food in the world. Then he puts them on a strict diet and exercise regime to get them back to their normal ‘small’ selves again.
