"Miss. Granger, under no circumstances will I allow you to put a bouncy castle in the middle of my classroom." Mcgonagall Said sternly to Hermione as the Gryffindor pouted.
"But why?" Hermione was not going to give up without complaining.
"Because, Miss Granger, a bouncy castle in the middle of a classroom will only cause a distraction and none of my students will get any work done. Much like right now so I suggest you all get back to work." At her words everyone went back to transfiguring their rocks. Except Hermione who simply continues to stare down Mcgonagall. Suddenly Hermione's face lit up in anticipation.
"Professor? What if I were to transfigure the bouncy castle? Then I would still be working." Mcgonagall never got the chance to answer before Hermione turned, pulling out her wand and point it at the desks moving them to the side of the room. Then turning to a rock that had fallen off one of the desks. She waved her wand and then the rock started expanding an contorting until it finally stopped growing and there was a bouncy castle in the middle of the transfiguration classroom.
Mcgonagall could do nothing but stare slack jawed as Hermione smirked triumphantly and the rest of the class cheered and swarmed into the newly formed bouncy castle
"See professor, completely educational." Hermione turned to see that Mcgonagall was gone. "professor? Where'd you go? Oh well, Move over guys!" and with that Hermione joined her fellow Gryffindors in what she dubbed the Palace of Bounciness.
Harry bounced over to her "You do realize this is going to have to go in the letter to the DA members right?" he asked her, though the seriousness didn't reach his eyes and the fact that his hair was messier than usual because of the jumping didn't help either.
"I figured, but it was so worth it. Do you know where Mcgonagall went?" she asked after a moment.
"Probably to get an aspirin and have someone else come deal with this." Hermione simply nodded and continued bouncing.
The group wasn't bothered until Dumbledore showed up to usher them off to their next class. Coincidentally Mcgonagall's next class showed up at the same time as Dumbledore. Even worse for Dumbledore the Weasley twins were in that class and as the fifth years got out to head to charms they ran in and started jumping around, Shortly followed by Lee and several other classmates.
The headmaster sighed and gave it up as a lost cause considering Minerva wasn't even there to teach the class anyway. With that he walked out and to his office where he immediately changed the password in hopes of avoiding being dragged into a situation like this again.
Several minutes earlier:
Mcgonagall got as far away from that crazy scene as fast as possible. She thought Granger was the sane one but it seems Spending so much time with Potter and the Weasley's had corrupted her. With that saddening thought in mind she headed off to the headmasters office to let him deal with it while she took a nap.
