Mix milk and vinegar in a bowl and let stand for 5 minutes so that the milk goes sour.
Mix flour, sugar, baking powder, bicarb soda and salt in a bowl.
Mix together egg, butter and soured milk, then beat in flour mixture until lump-free.
Heat a large frying pan over medium heat and spray with cooking oil spray (or butter). Pour portions of the batter into the pan and make 4 large pancakes (about 15cm diameter) and 4 small pancakes (about 8cm in diameter). When bubbles form on the top of the pancakes, flip them over and cook on the other side.
Set 3 of the large pancakes on 3 large plates. Cut the small pancakes in half and place them as pig's ears next to the large pancakes. Cut around a small glass to make three snouts from the remaining large pancakes. Place 2 blueberries on each as eyes and two more for nostrils. Place half a slice of orange as the tongue.
