Prize Bubbles are one of four items that you collect as you journey through LittleBigPlanet. Along with Score Bubbles, Keys and Collectabells, Prize Bubbles help motivate you to make progress and compare your effors to other players. The first time you encounter each Prize Bubble, you will see an item floating in the middle. These items can be new Materials, Outfit Items, Stickers, or Objects. The second time you encounter the bubble by playing the level again the prize bubble appears as an extra large score bubble.
