Where do you get ribbon cable?
I bought mine from a local hobby store; HobbyTown USA (http://www.hobbytown.com/). The ribbon wire was meant for those mini-electric train sets. Those train sets, can use up to 17VDC, it's crazy how dangerous those things are and yet kids back in the old days had to be smart to play with them or they'd electrocute themselves.
Where do you get the little kid to stick inside?
That's too cute. I wonder what was going through that little girl's mind. "Oooh stuffed animals!!"
