The ball in our fanart Harry Potter Golden Snitch Sticker is the most important ball of the lot. It's hard to catch because it's so fast and hard to see. It's the Seeker's job to catch it. The Golden Snitch, also called the Snitch, was the third and smallest ball used in Quidditch. It is a walnut-sized gold-colored sphere with silver wings. It flew around the Quidditch field at high speeds, sometimes pausing and hovering in place.
