I know of people who tried to send Surprise Eggs from Germany to the U.S., and the eggs always got taken out of the packages by US customs. I believe this is because the U.S. states that toys inside of food (the chocolate) are dangerous and a choking hazard (huh, I ate that stuff during all of my childhood, and I am still alive!). I think there is now a New Jersey based company that produces eggs similar to Kinder Surprise eggs, but I do not know if they're any good.
Before I came to the States, I'd never thought that Surprise Eggs might be considered a dangerous good that Americans must be protected from (while they're all hoarding guns in their bedrooms, lol! ), but I guess you never stop learning.
