My dad got ds1 a little motorized plane on one of his work trips to Japan. On the packaging there was a little kid who is crying with the plane above his head. The packaging is all in Japanese so we could only guess what the warning is.
Turns out it's do not put this toy on your head because your hair will get caught in the wheels and it will be super painful. My brother learned this the hard way.
Re: Toy fail
The batteries are no longer in the toy, much to ds1's dismay.
