Psychotic Plot Bunny!
"Maybe it's hungry again." Ron panted as the Trio reached the greenhouses. "I am." Hermione shot him a look.
"Hey guys! Do you want to see my Independent Study project?" Neville asked emerging behind a row of potted plants. "I'm the only third year accepted into the program!" He held up a bright orange and red mushroom. "This has properties that will - AAAAAAAAAAAAAAAAAAAAH!" He yelped as the Plot Bunny leaped up and nibbled about a square inch of flesh off the mushroom. "NOOOOOOO!" Neville yelped. "That thing's got twice the potency of no-doz combined with hallucinogens!" The rabbit's eyes dialated fully before it started bouncing aimlessly around the greenhouse knocking over plants.
"We're trying to stop it, mate!" Ron yelled. "OI! PSYCHOTIC BUNNY! GET! OUT!" Ron grabbed a shovel and chased the rabbit back out into the hall.
"Sorry, Neville!" Harry apologized hurriedly to his friend now covered in soil and leaves.
"That's ok!" Neville said.
The Trio saw two tall redheads walking down the hallway toward the bouncing hallucinating plot bunny. "Fred! George! Stop! That's a mad rabbit who ate a hallucinogenic mushroom!" Hermione cried. "We need to do something with it!" She stared pleadingly at the Weasly twins who looked at each other and said in unison:
"Excellent!"
That's NOT the reaction I was looking for. Hermione thought as Ron and Harry laughed. Fred and George guided the rabbit via their wands into the next classroom they could find.
"Now, the incantation is simply this: Hilario!" Professor Flitwick said flicking his wand to demonstrate a cheering charm. The spell hit the bouncing rabbit and it started giggling. "Oh my -" Flitwick said as the class of Hufflepuffs started laughing hysterically. The rabbit knocked Flitwick off his chair. "Bad rabbit!" He yelled. The rabbit bounced on Flitwick's chair still cackling.
"Sorry, Professor!" Hermione said. She managed to freeze the rabbit in it's motion and summon it to herself. It was still cackling madly. "We're trying to contain him." To her horror it started wiggling again. Apparently any spell cast at it only lasted 30 seconds.
"Give it here, 'Mione!" Ron said. "I know where to take it!" Ron grabbed the rabbit and wrapped it in his long arms. The Trio plus Fred and George went up to none other than the Divination tower. "Give her hell, Plot Bunny!"
The plot bunny jumped out of Ron's arms and the first thing he did was knock over the little tea tables around the room. Though Hermione cringed at the sound of breaking china, she was relieved she wouldn't have to read tea leaves for a while. Professor Trelawney was sitting at a round table holding a large crystal ball and practicing her lecture when the bunny stopped under the table. As it had run for quite a while and had drank a bit of water beforehand, he did the only natural thing: lifted his leg and relieved himself on the table and Trelawney's clothes. She screamed and knocked her crystal ball off the table. "Sorry, Professor!" Harry called. "We tried to stop him from coming up here, but we figured you'd see him coming anyway!" Trelawny opened her mouth to retort when Fred and George bribed the rabbit over with a carrot seconds before the five of them disappeared below the trapdoor.
