The SS Einstein is a spaceship derelict detected by Kryten while in artificial reality during "Back in the Red III". During this time, the former Starbug crew believed they had escaped imprisonment inside Red Dwarf by escaping in a Blue Midget shuttlecraft. Kryten was eager to get to the Einstein to get to more of a resource Blue Midget was critically low on--fabric softener. He was greatly concerned about everyone's linens getting all "bibiley bobbley".
