I’ll write the final book (or story or whatever you wanna call it) here because I like lamprey. Wait, this is off topic but would if Subnautica (or below zero) had a huge Lamprey leviathan? It would be cool and could be as long as a ghost leviathan (they look a bit cute though.) and it gets onto your cyclops somewhat like one of those lava leeches in the inactive lava zone (and active lava zone. When it got onto your cyclops, it could make a not too big hole on your cyclops with its tongue (Lamprey have a tongue with many sharp cone shaped teeth that they use to cut open their prey’s skin.) and you would have to repair it with a repair tool before the room flooded. It’s not that great of an idea, but it seems more of an ok idea.
