What does the dubious creature do?
It followed me around, I led it to the other fish in the room, I saw it after getting stung twice and ate balloon shrooms... I'm not sure if I'm missing something here...
Apparently. There is some weirdos in the Discord Server for Delusria, does some gifs or pictures that says "The Endless". The creature is called something Ana-something something. I cannot recall.
It is some sort of small water creature, that has two weird tentacles as hands to interact with stuff and look kinda like a very evolved trillobite, almost.
That is all i know of it. I did not bother to research it. Hope that answers your question, even if limited.
Take care!
