Another stylized shot of my custom LEGO Space Explorien magnifigure, in front of the Moth Nebula painting and the makeshift lunar surface from the previous Ferromagnetic Planet display. I still have several LEGO Explorien fossil tiles from my childhood! In the LEGO Space lore, Exploriens were a faction of scientific astronauts who would uncover ancient alien relics on planets, basically like space paleontologists. Their key components were magnetic fossil tile pieces that came with the sets.
