After reviewing every lake in the Fish-o-pedia, Monster fish will display at bottom of the lake information. It will list which season and time of day to select when entering the challenges. Monster fish are found while driving the boat around the lake and are identified by a blue dot. The dot will appear when you get close to the fish. Use the 80 pound line and the drag set to 1. The fish will eventually become exhausted and can be reeled in easily.
10 Perfect Cast hint:
In the 10 Perfect Cast further than 85ft, you are given 3:00 to complete. This is almost impossible given the time it takes to reel in your cast. However, there is an exploit; cut the line after each Perfect Cast of 85ft or longer. You can cut your line by pushing the B button. This same technique can be used in the Casting Rings Cha.
