You talking about that 21 pound fish (it was either 20 or 21, I forget because it's been so long), yeah it was a bitch to catch. It was a bitch to get to your lure, too. The secret lure was needed to catch the sucker, and even after that it puts up quite a struggle. Me? I caught it a couple of times (not bragging or anything) and each time took a while. I sure hope they have bigger fish in TP. It would be funny if they had one as big as Del Lago from Resident Evil 4.
But, actually, I think the "loach" they refer to is the Arwing and not the fish. Reason being is when they first spot the Arwing in the video, one of the players says "there it is, the Hyrulean loach".
