Minerva McGonagall, Deputy Headmistress of Hogwarts, Gryffindor Head, Transfiguration Professor, walked into her classroom, planning to lecture about the transformation of a tea kettle into a fish tank. Facing her class for the first time since she came in, she gave out a loud gasp of surprise, and horror.

"Why in Merlin's name is there a monkey in class??" she screeched, before getting into a sneezing fit.

"That's Parvati, Professor," Neville replied. "It was a potion she drank that made her like that."

"What," McGonagall asked, sneezing, "potion was," she sneezed again, "it?"

"It was a defective version of the Somnium Venenum, Professor." Neville informed.

"Miss Brown, would you," McGonagall sneezed, "please bring Miss," another sneeze, "Patil to the hos-" a sneeze once more broke her sentence, "hospital wing."

Lavender however, was not paying any attention to McGonagall as she was rather...busy. And unfortunately, McGonagall did see why.

"Miss Brown!" McGonagall screeched, "What are you doing," a sneeze, "to Mister Potter?!"

Lavender, who was preoccupied with Harry at the moment, ignored her professor, keen to finish her work. Professor McGonagall, who wanted Parvati out as soon as possible, asked Neville to do so instead.

She then proceeded to yell at her. "Brown! You will stop that at once! Let go of Mister Potter and listen!" Lavender finally pulled away from Harry, smiling contently. Harry was looking quite dazed, and his hair was an odd mix of pink and yellow, which caused Ron to snicker and for Hermione to disapprove.

"Now, what happened to all of you?" McGonagall asked, face covered with red blotches.

"Like Neville said Professor, Hermione's potion did these," Ron explained.

"Miss Granger?" McGonagall repeated, flabbergasted.

"Is this true?" she asked.

"Yes, I must profess" Hermione admitted meekly.

McGonagall continue gaping at Hermione before breaking out into another sneezing fit.

"Merlin's beard! Will," a sneeze, "someone please," another sneeze, "bring Miss Patil," a big sneeze, "to the hospital wing!" the loudest and wettest one yet.  

Dean who was sitting in front of McGonagall, flicked off the piece of imaginary dust only to rip out a portion of sleeve. Seamus, who was sitting beside him, started crying as McGonagall had sneezed on him.  Dean proceeded to tap him comfortingly on the back, only to choke him as Seamus started spluttering.

Parvati was jumping up and down on the table, causing McGonagall to sneeze more. Neville was trying hard to get her to calm down, but only got scratched by the hyper-active monkey.

Lavender had wandered out of the class and was in the Charms corridor snogging every guy she came to contact in. Ron was teasing Harry about his hair which was a bright neon pink that reminded him of Tonks. And Hermione was handing her hanky over to McGonagall whose face was red and eyes, small squints.

McGonagall's head spurred as the seconds passed. She had to get out of there!

"Class," she sneezed, "dismissed!" she instructed before striding into her office, leaving the students to their own insanity.
