(Ron's pov)

I woke up to the strangely frantic whispers of my dorm mates. I tried to sit up but I was caught by something sticky. I opened my eyes, to see a giant spider web surrounding my bed with plastic spiders.

I shrieked when one fell on me. I tried to lift my arm to get the thing off me, but I couldn't move. I realized that the spider webs were holding me down. I thrashed my arms and legs until they were freed and I sat up, my pillow coming up with me.

"What is this? Why can't I get my pillow off?"

"Someone poured tree sap on us. We need to get a shower before we can go to breakfast."

(Fred's pov)

I woke up to my twin shaking me.

"Fred, get up!" The tone of his voice forced me to sit up. I looked around the room which was filled with colorful bubbles. I grinned when a blue bubble floated past my face.

"Did you do this Forge? I don't remember having this kind of prank idea."

"No I didn't. I thought you did!"

"Yo guys! Why don't you forget commenting on the bubbles and help me pop them?" Our friend Lee Jordan asked as he poked at the bubble in front of him.

It popped with a beautiful shower of green sparkles, and my twin and I began popping the bubbles, until we noticed that something was off.

"Gross! What is the horrible stench!" George asked, and we realized that the bubbles we were popping had sprayed us with some kind of horrible smelling potions. We decided to get ourselves cleaned up before getting ready for the day.

I watched as my Slytherins all arrived to breakfast together as usual. I especially watched the first years.

I knew that something big was going to happen this morning. Harry had explained that the first year snakes had a big prank planned on the house of the Lions. He wouldn't give me details, but he did warn that it might get a bit loud.

I looked up as two of the three remaining houses trickled in, and soon the only missing students were the Gryffindors, whose table was completely empty.

Everyone who was present had been eating their meals, and checking their schedules, when the hall suddenly echoed with a series of shrieks and screams.

Everyone turned towards the door, and the reason for the disturbance soon became clear when the Gryffindor students finally entered the room.

I understood just what my snakes had done, and I had to struggle to keep my mask in place, and not show my amusement when the whole of Gryffindor had been gender swapped. All of the male Gryffindors were currently female, and the female were male at the moment.

The rest of the Great Hall burst into laughter, except for my snakes, whom instead kept straight faces, apart from their eyes, which shone with amusement.

I thought back to the conversation I had with Harry last night. He had mentioned that his group had planned an attack on the Gryffindors. He didn't give me details, he just told me that while all of the teachers were focused on the students, that it would give me time to go after the stone.

I thought about the duplicate that the Potter heir had given me. It appeared perfect. Same size, weight, and color of the fabled stone, even the same aura.

Harry had assured me that whoever planned to use the stone would be in for a rude awakening. I shivered at the feeling that those words gave me. It told me that Harry fully expected Dumbledore to desire the stone if Voldemort did not acquire it.

I looked up at aforementioned Headmaster waved towards me.

"Could you brew up a potion to fix this situation Severus?" He asked. It was perfect timing. I told him that I would try but I already knew that no potion would work. Harry had already assured me that the prank will wear off in a few days, and there was no counter curse or potion.

As it was I proceeded to take some samples from the affected students to 'study' in order to make it appear a if I had tried.

When I made it to my personal lab I applied several powerful wards on the room, door and fireplace to ensure that no one realized that I had left, before making my way to the forbidden corridor. I made quick work on all of the feeble protections and had retrieved the real stone.

It wasn't long before I was brewing in my lab, making it appear as if I was working on a 'cure'.

My friends and I waited until we were safely in Slytherin territory at the end of the last class, before we let our masks fall.

"That went better than I could of hoped!" Blaise smirked.

"Did you hear what Weasleys shrieking in Flying was all about?" Pansy asked.

"I happened to be close enough to hear him ask Madam Hooch to go to the Infirmary just before we were dismissed." Draco replied, before turning to me. "I also saw you disappear when Weasel was escorted out."

"I was following Weasley of course. I wanted to see if it had anything to do with the prank."

"And?" Blaise questioned.

"Apparently he was experiencing cramping in and odd place. Madam Pomfrey told him that he was going to be having some...feminine problems..." I smirked. Everyone within hearing range, even some upper years began laughing.

I looked up when I heard the common room door open. A nervous looking second year, handed me a note.

-Come to my office. SS-

I stood up, pocketing the note and nodding to the older student. I told my friends that I would see them later and left the Common Room.
