Hmmm… Leading into the credits may be the tricky part. Just playing with it in my head, I have an idea but I can’t think how to express what I mean without humming. (Can’t do that, with multiple sleeping family members and myself about to join them in sleepybyland…)
I wouldn’t want to remove the ghosts, myself. If anything adding Ben would be nice. (Even if he’s goofy! It’s okay for him to be.)
