Midway through Part 1 there is a quest to catch a special fish which appears with a purplish shadow (Fódlandy).
However, I found it again when I was in Part 2 on the day where the special Fish of Mystery event was going on. I was using the 5 star bait, and after catching 3 Goddess Messenger, purplish fish shadows started appearing with "strange fish shadow" tags (they were the Fódlandy). After catching 2 and failing to catch one, they stopped appearing (also no more rainbow fish shadows with the Goddess Messenger appeared again).
I searched online and haven't found anything about it. Is it a bug or just a feature not yet discovered?
