Oh, the snail had some kind of parasite that causes their eyes to expand and makes them seek out more light, so birds will eventually eat them. The parasite's eggs will end up in the bird's droppings, eventually being eaten by another snail. So the cycle continues...
Hmm now i realized something the eyes look like some sort of bug now, dunno if that was the point, or it's just the eyes expanding and getting all weird but the parasite being still inside, instead of "replacing" the eyes.
Usually, the parasite extends tubes full of eggs into the antennae of the snail, which enlarge the antenna and pulsate. Most likely that's what's going on here. So, the eyes are still eyes, but they've been forcefully expanded by the parasite's body.
that reminds me, how much it bugs me when yukkuris go "certain food takes it easy" if the food lets them eat it, but if the food "dares" to want to live and run "it doesn't take it easy", specially when they go when someone wants to eat them that "they want to take it easy" by not being eaten and it makes one go "so the mister bug that you called uneasy for not letting you eat it didn't want to take it easy by living as well?".
Maybe i'm just too strict or something, but it really makes me wonder how self centered the yukkus can be, or how far it goes.
Yeah but they also call flowers "Yukkuri" and butterflies are also called "yukkuri" and such. And if they eat something like a cactus or any plant that would harm them, they would also call it uneasy, even if it isn't a spiny type.
So it feels more like "they take it easy because they let me eat them and take it easy!" than "they take it take it slowly".
