We kind of love that this packaging has a Choking Hazard on it since it works on two levels. The facehuggers are pretty small, so they're literally a choking hazard, but also their raison d'etre is to become a choking hazard. Presumably the U.S. Consumer Product Safety Commission hasn't yet come up with guidelines for Chestbursting Hazards or that'd be on here, too.
Guaranteed free-range and cage-free, this set of a half-dozen Xenomorph eggs from Alien includes 3 which have hatched out the cutest little facehuggers. These glow-in-the-dark eggs come in a slightly-oversized but not-enough-to-be-noticeable-unless-it's-next-to-another-egg-carton container. That's why we suggest you wait until the next time you run out of eggs to slip these into the fridge to freak somebody out.
