Disney Universe is filled with lots of things for you to pick up and collect.
Coins
Coins are everywhere. They can be found just lying around. Smash some objects and more coins appear. You even get coins when you defeat enemies. Get as many coins as you can so that you can unlock new worlds and purchase new costumes that you have unlocked by rescuing guests.
Blue Stars
Blue stars upgrade your tool for the costume you are currently wearing. They can be found by themselves in some levels and are sometimes locked in chests. Look for a key somewhere in the level, pick it up, and then carry it to the chest. Keys open chests and inside you find blue stars.
World Collectibles
Each world has its own unique collectible. There are three collectibles in each level, for a total of nine collectibles in each location and 27 in each world. Get all three collectibles within a level and you can unlock music, concept art, or character models for the current world.
