Guys when you advance the multiplier to special w/l is there in actual shot you need to make? I've owned the game for years but today I noticed when I got the special w/l light on once in awhile a new sound I never heard before would go off and I got lucky on a multiball and cradled the balls and when it started going through the high scores a new music track started. My four year old son immediately ran over as he never heard it do that. Anybody experience that?
