The gooballs have come back to MOM to know what had happened. Sadly all of them went to the World of Goo Memorial and Recreation Center where they are currently being stored and helping in fixing the World of Goo Corporation.
After the big explosion of the Virtual World of Goo Corporation, it damaged a few areas in the Information Superhighway.
Since the gooballs couldn't come to meet MOM, they asked their old friend the two Application to reach MOM. But the explosion destroyed all nearby lands and surfaces so the Application were confused. They had to reach MOM in anyway possible!
