Hugo chuckled. "You're welcome I guess," he said, wiping some flour off his face. "We should," he nodded and pulled out his wand. Which was also white. He blew some flour off of it and pointed it at the floor. "Scourgify," he said and the flour slowly disappeared from the floor. "Don't underestimate the power of purple," Hugo said. Before the incident, purple had been one of Hugo's favourite colors. Now it was blue and red all the way. "By the way, look what I did," he said and took the little velvet pouch which had been hanging round Hugo's neck under his shirt. He opened the tiny little pouch and put his hand in it. His arm went down all the way to his elbow and then he couldn't go any further. He took a book from the little pouch. "Pretty good right?" he asked. He had been so proud when he'd managed to do the Undetectable Extension Charm.
