The Harry Potter Compendium

"As a surprise for Harry, they had painted a large banner on one of the sheets Scabbers had ruined. It said 'Potter for President', and Dean, who was good at drawing, had done a large Gryffindor lion underneath. Then Hermione had performed a tricky little charm so that the paint flashed different colors."
