Grate the ginger and crush the garlic cloves, then chop the onion and pumpkin. Melt the butter in a large saucepan and add the prepared ingredients. Cook on a medium heat for 3-4 minutes, until the vegetables soften but do not brown.
Add the ginger, honey and Knorr Vegetable Stock and bring to the boil - simmer for 15-20 minutes. Stir in most of the plain yoghurt then transfer to a food processor and blitz until smooth.
Toast a few pieces of bread and cut out using a bat-shaped cutter. To create the cobwebs, slowly pour the natural yoghurt in round motions on top of the soup, then use a spoon to slowly pull the yoghurt into points.
Season and serve with the toast bats and a few novelty spiders!
