“The last of the Goo Balls” is a quote found on all of the last levels of chapters in World of Goo.
Regurgitation Pumping Station, Chapter 1
The last of the Goo Balls didn't seem to know that they were extremely delicious or about the nature of the smelly pit in which they found themselves. They said something about this being the last level of the first chapter... whatever that means.
The last of the Goo Balls didn't seem to notice they were in some sort of giant Beauty Pageant Machine. Pretty ones over there, Ugly ones over here. Personally, I think everyone is beautiful. Mostly me.
Happy New Year! The last of the Goo Balls didn't seem to notice... they were part of an internationally televised World of Goo Corporation Product Launch Event. The color pamphlet they were handing out indicates the product will change the world forever. Shhh...! They are about to reveal World of Goo Corporation's new 'Product Z'...!
Balancing on the edge of the Big Recycle Bin, the last of the Goo Balls didn't seem to know that they were extremely explosive or that all the mail files in the history of the Information Superhighway were about to be undeleted!
