The planet appears to be basically a black sea, with six large islands on it. These islands are all grouped in variance - ranging from grassy hills to a windy desert to an iced-over factory to a station for observing. The planet seems to have very little wilderness, and all the islands contain machinery in some form. For example, gears and blades are a common motif in levels and on the maps. A network of pipes criss-cross the islands, which collect Goo Balls and transport them to the World of Goo Corporation campus, on the northernmost island. The planet has a form of Internet, the Information Superhighway, but it was abandoned years ago. The World of Goo is orbited by a Moon, though this may be artificial.
