even if it was from arirals, i have no idea why they would build something like that, doesn't make much sense
plus this thing seems very similar to a "geom", a type of "entity" that was cut in earlier versions (at the time it was just left over dev cubes and spheres and stuff nose forgot to remove) jokingly called an entity/alien, i suppose it could be an actual kind of entity now and this is what this thing is
