Akemi's bell
I had to smile when Akemi's bell became a minor plot point in the third film, and that the guy says "She sounds like a kitten." When I was watching the first film, every time she was on screen I would wonder where in the hell our cat was, because I could hear his bell in the room but I couldn't see him. After a while I realized it was her. It's particularly amusing because in my years of experience buying bells for our various cats, I know damn well that they're like snowflakes- no two ever sound exactly alike. But Akemi's was a dead ringer for the bell one of our cats has been wearing for the last few years, close to an exact match.
I hope you enjoyed this gripping anecdote as much as I enjoyed writing it.
