Getting a 5 – 10 year old to scrub the good old pearly whites can be an hour long debate. Give them a Tooth Tunes toothbrush and they’ll be dashing to the bathroom to enjoy a 2 minute symphony in their mouth – that is until they get sick of the same old song/noises emanating through their skull (the sound comes from the toothbrush head). Hasbro might wanna consult the DAA, though, because the more pressure you apply the louder and better the sound gets. Last time I checked, more pressure ain’t always a good thing while brushing. You gotta go with the Star Wars addition: cool movie sound effects and phrases.
