Draco spent all his time riling Weasley and his friends up, as did many of the Slytherins. Pansy was happy to whisper threats from Chaser Warrington in Potter's ear. Draco had created a number of badges in the shape of crowns, and with Pansy's help, who was an amazing singer, he created lyrics mocking Weasley. They practiced the song for a long time. The badges all said Weasley is our King on them.
