The Action
Ron and Harry got up early and met Fred, George and Hermione in the common room.
"Which one of you wants to be Umbridge?" Hermione asked.
"Not me!" replied Harry and Ron at the same time.
"Fine, I will" said Harry.
"Thank you, Harry" said Hermione handing him a bubbling icky glass of Polyjuice Potion. "Here's yours Ron" handing him a similar glass.
"Drink up!" said Fred trying to hold back laughter.
"Cheers!" said George.
Ron and Harry chugged the potion and soon after they started the transformation. Harry's seams of his shirt ripped as he suddenly sprouted boobs. Ron's bright red hair turned bleach blond. Harry's pants ripped loudly as his butt grew about 4 times the size as it was before.
As they looked down at themselves and at each other they gasped.
"O.K. hurry you don't have much time," said Hermione. "Good luck!"
"Thanks!" said Harry.
Fred and George were rolling on the floor laughing. Harry and Ron snuck down under the Invisibility cloak, but Harry's butt still stuck out so he had to do a Divisibly charm on it.
They got down to the Great Hall and Harry whispered, "You know what to do, just pretend I'm Lavender, and I'll just pretend you're Ginny,".
They started aggressively snogging, stopping only to moan for dramatic effect. Soon students came and started laughing at them. Harry and Ron pretended to act surprised and embarrassed. Someone even got a picture! Dumbledore even walked in and saw them!
As soon as Harry & Ron could get away, they unlocked Umbridge from her office and got Malfoy out of the broom closet they had stuffed him in. They were quite surprised when they went down to the Great Hall!
