Harry and Ron ran inside the bathroom and the smell hit them like a blow to the face. It must have been about 10 feet tall and smelled like a sewer pipe exploded in their faces it looked like a potato was dropped on top of a larger potato and hit with an engorgement charm. "Run Hermione!" Ron shouted as he ran towards her trying to save her from the troll as it smashed sinks and stalls.
"Ron get look out!" Harry shouted running forward to try and help as the troll brought his club down but he tripped over a piece of door and fell forward as a few cards fell out of his pocket. "Argh" Harry said as he fell his duel deck flying forward, one of the cards landed face up in front of Ron and Hermione. Suddenly Ron and Hermione disappeared as a giant felt top hat with a question mark in it appeared where they were. "A magical hat?" Harry asked getting up but the troll, who had stopped when his prey disappeared brought his club down on the hat, it disappeared and there was nothing there. "Harry get us out of here!" Harry heard from behind him he looked back and saw another hat with Ron's hand reaching under the brim.
"Stay in there I have an idea" Harry said tapping Ron's hand. "Okay troll" Harry said as he gathered his duel deck including his already used Magical hats :It's time to duel!" He shouted whipping his robes behind him. The troll lumbered forwards while Harry put his cards into his duel disk the troll was almost upon him when Harry set a card face down causing it to land right in front of the troll as it took a step "You've stepped on my trap card Trap Hole" and a hole opened up underneath the troll dropping it down to the next floor where it hit it's head and fell unconscious
"Game over" Harry said and all his cards disappeared releasing Ron and Hermione "Harry what just happened mate?" Ron asked looking down the hole "That was Muggle duel" Harry replied "and I've never lost" they turned around as the teachers rushed in drawn by the Raucous noise they had made.
