Pranksters
Siri, Petra, and Kate had been quietly working on a plan. By the third prank on Petra, they were ready to trace the spell back to its caster. They had also been putting together an appropriate revenge, and one that would be fairly hard to trace back to them. So, everyone was surprised when nearly two weeks later, Simon Thomas and his older brother, Samson, came into the great hall for breakfast smelling strongly of lutefisk with robes that flashed the word "Meanies" across the back in neon blue letters.
On their way to the first class of the day, Elaine Krenshaw, another first year Gryffindor, pulled Petra aside.
"That was awesome, Ashton. He's the one who did your hair green, right?"
Petra just smiled. She and the other two girls had already decided that they wouldn't take outright credit for the prank. It would give them some measure of protection from getting in trouble with the teachers and from retaliation for the prank from Slythrins. Besides, it was kind of cool hearing all the rumors about who was responsible and being one of the few people who knew the truth.
It could have ended there with that one prank. However, on their way to Herbology two days later, the girls accidentally walked in on one of Pol's friends bullying a second year Hufflepuff. When the Slythrin girl noticed her audience, she made her position on things clear.
"You keep your mouth shut, or your parents will be hearing things they won't like, Sirius Williams."
Siri's face took on the same mask she wore after receiving the letter from her parents. She nodded curtly, and the girls continued on to class. The second class was over, however, she turned to Kate and Petra.
"So what can we do that will humiliate Shivani in front of the entire school?"
Kate raised an eyebrow. "I take it we're pranking her?"
"Yes."
Two days later, Shivani Azad's long black hair was liberally spotted with yellow and purple polka-dots. It also started a trend for the girls. Mess with a Gryffindor and you'll be pranked within a week. Of course, their streak of good luck in not being caught didn't last. But it was a rather minor prank and their first offense, so the girls only lost ten house points all together between them, and they worked hard to make the points up in class the next few days.
It wasn't an all the time thing, and it wasn't like they were being compared to the Weasley twins or anything like that, but the girls rather reveled in it all. It was rather fun being sneaky.
