So I just discovered something neat with FunHouse on my own accord which I'm willing to bet some people know about but I can't imagine this being common knowledge because I've played FunHouse a bunch in Pinball Arcade and a couple times for real and only JUST discovered this:
As everyone knows, you hit stuff to get the clock in the game up to 11:30, lock a ball to get to 11:45, and lock another ball to get to Midnight, which leaves you with just one more shot into Rudy's mouth to start multiball. However, when you initially get to Midnight, the music just sort of slowly dies, giving a sort of sensation of falling asleep. 99% of the time, this will always sound the same.
HOWEVER, if you start the regular Frenzy mode and lock a ball to get midnight, you'll get to hear the Frenzy music die in its own unique way! : O
I'm going to pay a little more attention to this to see if it's possible to hear other tunes in the game die out from getting to midnight. The attention to detail the game designers have put into many of these pinball machines, knowing that certain state combinations would be possible and having special cues and graphics and music and such to deal with it all... it's really freaking cool and one of the things I'm enjoying most about pinball! : D
