You know that thing from every home economics class where you babysit an egg? This is like that. Only this egg is roughly football shapes and looks like the shiny carapace of a beetle. It's also weirdly warm like a rock left out in the sun. If your character wants to participate in holding an egg for an hour or so, please sign up here. They aren't required to have it constantly, but it's strongly encouraged that the egg be in someone's possession at all times.

After all, you never when something might come slithering out of it.
