Joy, Sadness and Bing Bong entered Abstract Thought when the latter claimed it was a shortcut. Soon after they are in, two Mind Workers arrive to analyze the concept of "loneliness". However, as they see that there seems to be something inside the room already, they activate it to clean it up beforehand. The two Emotions and Bing Bong are suddenly taken through the extraction process, becoming progressively simplified in shape until they are just lines of color. They succeed, nevertheless, to escape before they are completely deconstructed when Sadness realizes they can exploit their temporarily two-dimensional state to slip through the door.
