These past few days, Su Er had gone to Snape's after dinner every day to work (get beaten up). In truth, the wisest thing he could have done was stay away while the professor was in a foul mood.
What Neville had done in Dark Magic Defence Against the Arts should have stopped being a hot topic after a few days, but the trouble was that a little figurine had suddenly become popular in the castle-the kind that moved!
-a cross-dressing Snape figurine, made from a lump of clay combined with magic.
Su Er could have figured out whose handiwork this was with his backside. No one besides the Weasley Twins of Gryffindor would have had the nerve.
They had most likely spotted a business opportunity in this. The young wizards could buy a black-robed Snape figurine, then use their imaginations and Transfiguration to change its clothes.
When Snape searched Harry's satchel during a Potions class and found a figurine wearing a bright red dress, he was furious.
He viciously deducted fifty points from Gryffindor, then tracked down the culprits as quickly as possible.
But it was no use. To be honest, the Weasley Brothers' figurine required no technical skill whatsoever, and it fell apart on its own once the magic wore off.
So even if the Weasley Brothers stopped selling this toy, some young wizards secretly made their own and dressed Snape up for amusement.
There was no helping it. From first year to seventh, almost everyone outside Slytherin House had suffered at Snape's hands to some degree.
One could say that Snape's reputation in the castle was maxed out, provided a minus sign was added in front.
Back to the matter at hand: on the evening before the full moon, Snape left him alone in the potion preparation
