The opening credits on the dvd are the original opening credits as designed for the show's first two seasons...but, you'll notice, the same people are listed, whether they worked on that episode or not. It's a ''generic'' opening, as the REAL openings had all those sponsor tags and the like (and were probably only filmed in B&W)
If you want to see what these really looked like, go to Toontracker.com and hit the appropriate links...where you'll see that Wilma did, indeed, have a mouth in the closing credits.
