THIS THE SKULL OF THE THING THAT ATE THE GARGANTUAN LEVIATHAN, THE LOST RIVER IS INSIDE OF ITS SKELETON; AND THAT EXPLAINS WHY THERE IS SO MUCH DEAD STUFF IN THE LOST RIVER... BECAUSE THIS THING ATE THEM; THE SKULL (THE ENTRANCE TO THE LOST RIVER) IS SOMEWHERE OVER HERE; AND SINCE NO ONE HAS FOUND THIS YET... I SHALL NAME IT, AND I HENCEFORTH DUB IT "THE PUDDLE COLOSSUS" OR SOMETHING LIKE THAT BECAUSE THIS THING IS SO BIG THAT THE OCEAN OF SUBNAUTICA WOULD JUST BE A DEEP PUDDLE TO IT
