Who: The Marauders + the affected populace [aka all students] What: James's birthday prank! Where: All over Hogwarts! When: Sunset, 27th March Status: Incomplete Rating: PG-ish
Oh, how maliciously wonderful this prank would be. James had been preparing it for weeks, all in celebration of his 17th birthday. This was A. Big. Deal. As he stood on the ground floor, just around the corner of the Great Hall with invisibility cloak in hand, he palmed the stone in his trouser pocket, itching to let the others know that it was time. He'd cast the Protean charm on inconspicuous stones to keep the other Marauders in the loop. When they felt their individual stones warming up, they would know that it was time to cast their part of the charm from their locations.
A slow grin spread on his face at the thought of how everyone would look, and how some of them would smell, before the day was out. The charm would last for exactly twenty-four hours, from sunset that evening until sunset the next, resulting in Gryffindor-coloured students and dung-scented Slytherins, just for good measure. It wasn't subtle in the least, and while he knew that he'd probably rack up a month's worth of detentions, it was worth the risk to pull off their most brilliant prank yet. That would teach those Slytherin gits to get cocky about their win on the Pitch.
Soon as he heard the first tell-tale signs of students coming down for dinner, James threw the cloak over himself and stepped out from an alcove just beside the Great Hall, aiming his wand out and towards the centre of the staircase leading deeper into the castle. His hand rubbed the stone the set number of times until he felt it heat up between his fingers, signalling his mates that it was time.
