Invisible Harry frightens the bullies

In the background the shrieking shack sits on top of a snow covered hill for this popular scene from the prisoner of Azkaban. I have chosen brickheadz style characters. Malfoy has been pelted with snowballs. Crabbe has his trousers round his ankles and can be tipped forwards, Pike can be spun from side to side by his outstretched scarf. The perpetrator of all this mischief? Harry in his invisibility cloak of course! Detectable by his footprints and glasses.
