Why am I getting slapped around by giant fish?

Question

I'm playing Recettear, and in the "Jade Way" dungeon, I appear to randomly be assaulted by screen-wide, giant fish.

They're not particularly hard to dodge (once you stop being surprised by them) and don't deal much damage, but I'd like to know what's causing it in the first place. Is it a special attack of one of the enemies?

Answer 1

It's not a special attack done by any of the enemies. It's one of the random trap-type occurrences that can happen in a square, like the rocks falling. There's really no way to predict it happening at all. You just have to dodge carefully.
