Author's Note: This is a story written by my sister Joanna (with a little help from me).
It was noon and the sun beat down on the grounds of Hogwarts. Mrs. Norris was roaming the hallways as usual, when she spotted two suspicious students loitering near a restricted corridor. Filch's kitty companion may not have recognized them, but they were, in fact, Fred and George Weasley. The twins were in their second year, and already they had discovered pretty much all of the secrets that lay installed in the walls of Hogwarts. However, this was the first time they had ever been down this particular hallway. At the moment, they were scoping out the area, before making their move. Upon seeing Mrs. Norris they knew it was time to act.
They hurried down the corridor. Filch would be along any moment. They had to act quickly. They ran to the end of the hallway, ignoring the potions storerooms on either side of it. They could raid those later. When they reached their destination, they emptied their pockets. This was going to be the best prank they've pulled yet. Just as they heard Filch's heavy, uneven footsteps reach the other end of the corridor they set the stink bombs. Then they ducked into a conveniently placed abandoned classroom where they would be safe from the fumes.
"Com' along Professor. I kno' they're in there." Filch was talking to someone.
"It better not be Lee Jordan getting into my gillyweed supply again." It was Professor Snape! This was too good to be true.
The second the two adults walked into range of the bombs, they set off a pressure plate triggering the bombs. There was an explosion of stench and foul, green fog. Filch made an unholy sound, something akin to a dying cow. Snape, on the other hand, kept his composure.
"Stink bombs, typical. Well, obviously my storerooms are quite safe. This was a Weasley prank once again. No doubt, we won't see them for the next few days. They always seem to disappear after these things. I will speak to Jordan for information, but I doubt that will yield any results. Good day, Filch. Have fun cleaning this up."
The potions master then left, and Filch spent the next few days cleaning that corridor. True to the professor's prediction, no one saw the twins for the next two weeks. There were, however, several mysterious reports of disappearing stashes of sweets, but no culprits were ever caught.
