Solaris

You heard a shuttle land outside the landing pad. While you were checking your calendar, it was scheduled to deliver supplies to a lonely station above the mysterious planet Solaris. It was supposed to be an autonomous shuttle, carrying only supplies. But after you suited up in your space suit and went to check it out, you heard someone knocking on the door. Unsure what it was, you used the automated floor to maneuver the shuttle into the hangar, and after the hangar was sealed, you opened the shuttle door, and there she was. A cute donkey girl, in the same uniform as you, but looking completely confused by the whole situation.
