Fish Cannery question

I have just played this stage and I remember the last time that I played this stage that there was a way to do something to activate a fight with that humongous fish that is peeking through the glass at you in the room with that chair in the center. The fish is being held in a vice by those cranes that you can see when you are at that one part where you have to cross over the water while avoiding being eaten by that one fish you have to distract with the other fish that hang down on that pulley that moves them over the water. Does anyone know what I'm talking about as far as being able to activate some switch or something to release that humungous fish that is bigger than all the rest of them in the fish cannery? Has anyone ever been able to release it and have Daxter fight against it in that room with that big chair? I know that I have done it somehow but I don't know now.
