Chapter three: The prank.

"Okay here's the corpse of the owl and cat tail you wanted. Now what?" asked Chelsea. Draco pulled out some celotape. "Stick them on their backs." Said Draco cunningly. "Let me guess, cat tail on Hermione's back and owl corpse on Harry's?"

"Ding ding ding! Yup you got the idea. Now hurry, there they go now, down the hill. Get em'!" said Draco. Chelsea smirked and walked towards Harry, Ron and Hermione. "Hi, what's your name?" she said, slapping her hand on Hermione's back. "urm… Hermione…you?" said Hermione. "Chelsea….." She then whacked her hand off Harry's back. "And you must be Potter," Both pranks were secure in place. Harry looked at Chelsea. "Why did you smack me?" he asked. Chelsea paused to think. "Just being friendly I guess…" She began to walk down the hill to where Draco was waiting. "Hey! You didn't talk to me!" Ron shouted at Chelsea. "I don't talk to Weasley's." she said. Ron hissed. Draco was laughing when she got to him. "Perfectly done! Now watch when they realise what you did to them…" They sat down and shared a chocolate frog together. Hagrid was late.

Then suddenly… "AAAAAAHHH!!!!" Hermione screamed. "NOOOO!!!" Harry screamed. Draco and Chelsea burst out with laughter. Ron was crying. Hermione was shouting words of hatred at Chelsea. Then Hagrid appeared. "Right what is going on here?" Hargrid's low voice boomed angrily. "The o-owl…b-back…s-sign of inviting y-you know who…" Ron sobbed. Harry trembled. His scar hurt. Lots of things have happened to him in the past two days. He now hated Draco even more. And that new kid…Chelsea…he feared she was worse than Draco.

Then Harry lost it. He screamed b at Chelsea. She gasped and told him to p off. Draco was in hysterics. She had just done what he had always wanted to do. She wasn't going to get detention either because she is a newcomer. He wished he had done that on his first week. Hagrid grabbed Harry by the ear. "Right I've had just about enough of this. Harry I think you need a detention. You know swearing is not aloud. Come on, Snape would like a word with you…."
