Render Bugs:
Another Dino head can be highlighted in the 'Creating the Characters' section on the second disc. Again, press the RIGHT arrow key to highlight the head and then press ENTER. You will now see a feature called "Render Bugs", which is a series of clips during which the computer generated images didn’t turn out exactly the way the artists had hoped.

Disneyland Goes to the World's Fair Footage:
On the second disc of the set, go to a feature called 'The Production Process' where you can see a list of different features to choose from.

If you press ENTER now to select it, you will get to see a 5-minute clip that is an excerpt from the 'Disneyland Goes to the World's Fair' feature, which was originally broadcast on May 17th, 1964.
