That could work, saying it tastes of chocolate or is simply as rich as chocolate.
The fishing minigame takes place in chapter 2, so it's only gen 1 & 2 fish...
Mostly gen 1 to be honest, gen 2 didn't add many that could be fished up

I just checked the fishing tables in Gen II and yeah it seems to be mostly Gen 1 Fish, with the only Gen 2 being Corsula, Remoraid, and the Chinchou Line and with those 4 you kinda need to be picky.
Idk what is currently in the fishing mini game but an idea rather then have the MC fuck a Remoraid, fishing one brings a Mantine over. I think someone else has pitched this before but that's probably worthwhile.
