Undelete interface

Spoiler warning: Plot and/or ending details follow.

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 and files in the history of the Information Superhighway... were about to be undeleted!

—the Virtual Sign Painter

In the video game World of Goo, the Recycle Bin is a location in Chapter 4 and a key turning point in the story. The Recycle Bin is prominently featured in the level Deliverance, the last level of Chapter 4, and is mentioned in the level MOM's Computer.

The Recycle Bin's purpose for the sake of the player is the opposite of its usual purpose. Rather than being used for containing an ever-growing volume of deleted files, the player uses the Undelete Pill to send all of the Internet's spam to the World of Goo Corporation headquarters, which subsequently explodes from the overflow of spam.
