Only things that move fade, such as Bing Bong and forgotten memories. Bing Bong's rocket, the Train of Thought, and the remains of wreckages from Imagination Land (i.e. Graham Cracker Castle) didn't fade because they couldn't move.

Some things might take more time than others to fade. Plus, memories project an image but the orb itself doesn't move (so you could consider them to be an object that doesn't move). The film didn't really detail the mechanics of the dump, other than say that everything that goes in it is like forgotten.--Gray Catbird (talk) 25px-Gray_catbird_cars.jpg 15:25, May 27, 2017 (UTC)
