Coral of the Abyss - Frozen Ocean's Tail

Summary Whoaaa... This is the first time I've seen it myself...
That coral is caught up in quite the legend, I can tell you.
What was it again?... It grows where the colors of heaven and sea meet
and can no longer be distinguishable...
And so, this very coral embodies
the concept of "unattainable love."
After all, there's no way the heavens and seas can both be the same color, right?
Hmm? Well, hang on. Why is this here then?

Quest Text It's hard to say whether the pollen is the color of the sky or the color of the waves.
It falls like snowflakes while giving off a beautiful and tranquil color.

Summary This is an aquatic plant that usually grows in underwater caves,
but it can grow in regular caves as long as it's damp enough.
Legends say it blooms where the sea meets the sky, and that
since both are the same color, you cannot tell where one ends and the other starts.
Seems impossible, right? Perhaps that's why this coral symbolizes "unattainable love."
Such a moment is likely to never exist.
