Pac-Man World 3 (Model Formats unknown?)

So I managed to rip these files from PMW3's disc, However they don't have a specific format for them and appear simply blank. I was wondering if anybody can figure out what type of models these actually are by any chance? Blitz Games really are rather crafty it seems.
