(Uhh algebraliens birth eggs idk.)

You and your friend, Nine were just hanging out together in the woods near the Equation Playground. You were both just climbing trees or looking inside some broken down ruins. He was off a few metres away doing his own thing until he called you over. "Hey, dude.. Come over here!" Once you came over, Nine showed you what he was looking at. It was an egg, and it looked like it was one of your own species. It had just been left here on it's own. "Yo, I think it belongs to another algebralien! Who would just... leave it here? Surely the area isn't warm enough for it to incubate..." They crouched down near it, poking it gently, but not hard at all.
