Sixty-four Pixel Colonists

Hmm... so the mold has a bizarre, angular structure, a series of strands twisting together into a cohesive, self-similar whole... hmm, doesn't that sound an awful lot like the alien obelisk that appeared around the exact same time?!!?

That arm makes no sense. Whether they cut off their arm or just the sleeve, what was the point of sending it back to the base full of ordinary icicles? And again, whether they cut the arm or the sleeve, would they risk depressurization and loss of temperature control by doing so?

Also, the biologist is not named Izvor. Seriously.
