Flutterby™! : Pixar KnickKnack 1991 vs 2004 version

I was vaguely aware that, some time after I left Pixar, a friend of mine was involved in the remastering of Knick Knack from the original 1989 version (the label on this image, stolen from http://www.dvdfr.com/ says 1991, which I think is meant to reference the VHS release date) to the one that Disney released, but I don't know that I ever saw the actual change.
