Wood reached into the crate and took out the fourth and last ball. Compared with the Quaffle and the Bludgers, it was tiny, about the size of a large walnut. It was bright gold and had little fluttering silver wings.
“This,” said Wood, “is the Golden Snitch, and it’s the most important ball of the lot. It’s very hard to catch because it’s so fast and difficult to see. It’s the Seeker’s job to catch it. You’ve got to weave in and out of the Chasers, Beaters, Bludgers, and Quaffle to get it before the other team’s Seeker, because whichever Seeker catches the Snitch wins his team an extra hundred and fifty points, so they nearly always win.”
