This trophy would work better in conjunction with the following:
As part of the preceding trophy, you will be docking into several different robots to try and uncover their dances. You should also take note that the MAPPY, D.O.G., Electrosux, Snowman dispenser, combat drone, dummy drone, and turrets would also count as part of this. You should get this trophy by the time you're marching through Methuselah's Core, but should you not, don't fret as there are no "Point of No Return" moments; you can return to almost any location (except Starcophagus) to dock with other bodies.
Citizens, Maintenance workers, chess pieces, shepherds (not sure if you need to dock in all shot-types), turrets, Drone, dummy drone, and perhaps even the mod-MAPPY are all within this classification, I believe.
