Kinder Surprise Toy Egg

Which came first, the egg, or the toy inside the egg? Technically not an Easter-specific toy, but it’s an egg riding a skateboard. This is a hard plastic version representing the actual chocolate egg which would contain a toy inside it. So it’s a self-referencing toy. In case this makes zero sense to you, Kinder Surprises are chocolate eggs with a tiny plastic toy inside. I thought this was a generic term, but apparently it’s a trade name, like Kleenex or Xerox. I thought it was vintage, but it dates to 2014 according to the seller.
