Koshchei the Immortal. Version: marine.
Well, where else would the needle be, if not inside the shell?
It seems that Koshchei has decided not to trust anyone with his death anymore. He hid the needle right in the shell and now sits on it himself, like a real keeper of ancient secrets.
No chests in the oaks, no hares in the ducks. It's simple: a shell, a tail, and distrust of the world around you.
Perhaps this is the secret of immortality — to take control in your fins.🐚✨
