The opportunity was too perfect to miss. Harry crept silently around behind Malfoy, Crabbe and Goyle, bent down and scooped a large handful of mud out of the path.

‘We were just discussing your friend Hagrid,’ Malfoy said to Ron. ‘Just trying to imagine what he’s saying to the Committee for the Disposal of Dangerous Creatures. D’you think he’ll cry when they cut off his Hippogriff’s’


Malfoy’s head jerked forwards as the mud hit him, his silver-blond hair was suddenly dripping in muck. ‘What the?’

Ron had to hold onto the fence to keep himself standing, he was laughing so hard. Malfoy, Crabbe and Goyle spun stupidly on the spot, staring wildly around, Malfoy trying to wipe his hair clean. ‘What was that? Who did that?’

‘Very haunted up here, isn’t it?’ said Ron, with the air of one commenting on the weather.

Crabbe and Goyle were looking scared. Their bulging muscles were no use against ghosts. Malfoy was staring madly around at the deserted landscape.

Harry sneaked along the path, where a particularly sloppy puddle yielded some foul-smelling, green sludge.


Crabbe and Goyle caught some this time. Goyle hopped furiously on the spot, trying to rub it out of his small, dull eyes.

‘It came from over there!’ said Malfoy, wiping his face, and staring at a spot some six feet to the left of Harry.

Crabbe blundered forwards, his long arms outstretched like a zombie. Harry dodged around him, picked up a stick, and lobbed it at Crabbe’s back.

Harry doubled up with silent laughter as Crabbe did a kind of pirouette in mid-air, trying to see who had thrown it.

As Ron was the only person Crabbe could see, it was Ron he started towards, but Harry stuck out his leg.

Crabbe stumbled and his huge, flat foot caught the hem of Harry’s Cloak. Harry felt a great tug, then the Cloak slid off his face.

For a split second, Malfoy stared at him.

‘AAARGH!’ he yelled, pointing at Harry’s head. Then he turned tail and ran, at breakneck speed, back down the hill, Crabbe and Goyle behind him.

Harry tugged the Cloak up again, but the damage was done.
