so you CAN fish it anywhere else >.<The only specific spot for catfish I can think of in the ruins would be the barrel next to the vending machine on the east side. (Illusion took "like fish in a barrel" literally). Usually good for a catfish and hagfish. Otherwise it's caught fishing anywhere with the right bait.
As for the barrel next to the vending machine.....it's not a "fishing" action right? it's just a "pick up" action?
I always thought the 1 Catfish I got was from one of my girls fishing....haha
I will definitely try it out tonight when i get home and start getting my girls some petsssss
Thanks.
