It didn't even occur to me to try to grab the R2-D2 content, but I saw this thread and found a challenge. Done! Here's how I did it under Windows. Method should be similar for other OSs.
Download the full SBF from here: (I grabbed 2.3.4, the latest version)
http://sbf.droid-developers.org/cdma_droid2/list.php
Extract the archive with your tool of choice
Extracting the SBF itself was a bit tricky; there seems to be little information. I ended up using "MotoAndroidDepacker" (Google it; it's on some file-sharing site). I did "Open from file" then "Split to folder", and despite an error message, it left a folder full of smg files.
Download ext2read:
http://sourceforge.net/projects/ext2read/
Open the SMG files with that.
CG66.smg had some Star Wars-related .apk files in the symlink folder.
CG39.smg has the media files. The "media" folder has the audio, video, and bootanimation file. In there is everything!
