This is a concept from Broken Age, Act 2. This is an early idea for what would later become the Diamond Droogs. Since Alex's ship is an earlier model than Shay's ship, it was based around a DIAMOND pattern (four sides), instead of Shay's ship which is based around a HEXAGONAL pattern (six sides...see? Way more advanced). The Diamond Pals were left to their own for a hundred years or so while Alex was in stasis, so the idea was that they became scavengers, somewhat feral and formed their own little society.
