I'm looking for a fic where in one chapter most of the order member are professor at Hogwarts. Tonks, Bill Wesley, Dumbledore, McGonagall, Flitwick, Snape, Sprout, Pomfrey, & Lupin have a prank played on them by Harry and Co. They do it was breakfast. All of the teacher start sounding like their 'inner animal'. I don't remember them all but Bill is a lion, Dumbledore is a goat, Filtiwich is a mouse, Pomfrey is a hen, Lupin is of course a wolf...etc. Then when they leave they start talking normally but they kind of start looking like their animal. I know that Bill gets like this mane, Pomfrey gets some feathers. If you know this fic I would really appreciate a link because it is driving me crazy.
