Hobgoblin rides on his black panther across the sky, searching for jewels. There is a special ruby he has not yet found – the King’s Ruby. His home is on the other side of the world, in a house that has no doors or windows. The Hobgoblin’s passion is collecting jewels, big and small. But there is one ruby he has not yet found, the biggest and most beautiful of them all – the King’s Ruby.
