Because of some obscure law about the toy being directly inside “confections”. I guess a choking hazard or something. One of my best friends is an immigrant from Wiesbaden, Germany and she hates that we can’t get the “real” surprise eggs here. She says they are so much better. If you try to ship them from Germany you can be fined something like 75 Euro per egg or something but most of the time customs just steals them and eats them.
