It’s an articulated robotic fish! I recommend using the vessel mover mod to get the fish in its natural environment. After that, press space to stage and throttle up rocket engines to desired speed (fish is not able to swim on its own, unfortunately). To simulate swimming motion, alternate pressing the A and D keys. Tail is fairly effective as a rudder, so holding down A or D will allow the fish to swim in a circle. Front fins are used for pitch/depth adjustment.
- The version in the video uses a DLC part; I have since updated so that the new version uses all stock vanilla parts.
