"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.

Throwing a stone at a tree, Amelia got them to spin on the spot. She put her hand to her mouth to stop her from giggling at their stupid faces.

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

SPLATTER.

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 forward, 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 midair, trying to see who had thrown it. As Ron was the only person Crabbe could see, it was Ron he started toward, 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.
