Transferring Angry Birds Data

I was able to transport all of my Angry Birds progress from my Windows XP VM to my Windows 7 VM.  All the Angry Birds PC games store saved progress in two files: settings.lua and highscores.lua.  They get stored in your Profile's AppData or Application Data folders.  If you transfer these files over, then you retain all your progress.  What I haven't figured out is how to transfer the saved progress for Bad Piggies.  Although the core interface looks similar to the Angry Birds games, the saved progress is not stored in the same location.  Other than that, all the games work better on Windows 7 than they did on Windows XP.  Angry Birds in 1080p on a 42" TV is still amazing.
