Here’s an idea: a blind creature can move, but only one or two tiles at a time, no matter what their speed is, and only in scent or sound view, unless there’s another, not blind, creature nearby (to help guide them.)
I agree! Animals who are blind don't sit around waiting for other animals to help them get around, they use their other senses to navigate, which would probably be even be stronger due to the lack of one sense.
Could you do Lentita (pretend she's an adult), maybe stealing a healing fruit from a plant with another nicheling turned around looking at something else? I don't care what the other nicheling would look like
