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?
