As part of the Up DVD and Blu-ray, which will be available on November 10th, here is a special Pixar short directed by Ronnie del Carmen. Dug's Special Mission is a little bit of the backstory of what Dug was actually doing out there on this mysterious mission when we meet him. In the short, Dug is instructed on how to catch the bird by Alpha, Beta, and Gamma, but his instructions are really intended to keep Dug away from them.
