LOL we were just there in early September, and the Jawa's at Launch Bay *LOVED* the little red bike bell on my personal
scooter! They played with it for several minutes, one would wander away to trade with/interact with other guests, and the other one would come over and start "dinging" again!
There was a CM at HS who asked if he could try the bell, and then he started ringing it, and did an impromptu "Mickey Rap" that had everyone in stitches LOL
Quite a few of the Main Street characters got a kick out of the bell, and Princess Merida had a good time with it too!
I have multi-color changing LED undercarriage lighting on my scooter at night, and we got so many positive comments from CMs and characters on that also - so don't hesitate to dress up your device and have fun!!!
