Willy

It is not a starship, and it would take a much longer time for it to- but it looks very much like one. Dragonfly radiators stretch along its mimic-shipspine, glowing the dull red of something that doesn't need to dissipate so much heat. Its habitat section cannot spin, rotors being such a difficult assembly to make, but it makes a good imitation of it by twirling itself. It runs through the system on weak little engines, but its reactor still hums in a way one would understand. By seeming dangerous, it avoids getting into trouble.
