I bought some Magical Moments interactive pins off Ebay, for my kids. They look similar, but pin on. Parades and different attractions make the colored lights go crazy, apparently, if you put the switch on "Park" mode. If you have the switch on "Game" mode, you can play a "Simon" type of game. OH, and you can use it to make other people with these pins' lights go off, too!
I got them new in package, with battery inside plus extra battery, with all the instruction manuals, for about $2.50 each (I won auctions that had 2 or 3 pins included.)
These seemed a bit more young-kid friendly to me since no playing of games is required, it will interact and is inexpensive on Ebay!
