Odd Japan finds this Hello Kitty breath sensor at Rakuten, which will detect any hint of halitosis. Since your breath won't always be flattering, 'Hello Kitty's Fresh Kiss' helps you determine it's freshness in four levels. After blowing on the sensor, a kitty face will dictate if you need to pop in a few of those Mentos, or continue emitting a pleasant scent.
