They're squirmy and curious! Drag and drop living Goo Balls to build everything from bridges to giant tongues in this physics-based puzzle game. The millions of Goo Balls that live in the beautiful World of Goo are curious to explore — but they don't know that they're in a game, or that they're extremely delicious. Connect the Goo Balls to build a wide range of jiggly architecture, including: bridges, cannonballs, and zeppelins.
