Aren't Kinder eggs outlawed in the U.S?

due to hazardous parts inside the chocolate eggs? I ask because I saw some in my local Market Basket. I got two, one of them is a complete monkey figurine, the other is a viking character with a metal toy pole, which on one end has a viking hat, so you have to put it in the hole in his head. So are they illegal?

There must be something in America's water that makes them truly retarded. My mum gave me my first Kinder Surprise when I was 4 and I had no problems eating the egg then assembling the toy found inside the container without any parental assistance.
