George's Marvellous Medicine: Level 5

George hates his grandmother. She is a selfish, nasty, old woman. Is she a witch? One day, George has a marvellous idea. He makes Grandma a magic medicine from all the runny, powdery and gooey things in the house. "Perhaps she'll become a better person, or her head will explode!" he thinks. Open your mouth wide Grandma, you are going to have a nasty surprise! Re-told by Andy Hopkins.
