In (RE4) Resident Evil 4 Remake there are various requests to be found and completed. Most of them resides near the merchant and the typewriter. Most obvious on walls and as blue notes.
These requests are similar to side quests in that they supply us with optional side activities. Sometimes we will be required to locate various collectibles, other times to destroy specific objects.
As a reward we are mostly rewarded with Spinels, which can then be sold for ptas to the merchant. Each chapter has at least one of these requests that we can try to solve.
Once you have successfully managed to completed the required task we can then speak with the merchant in order to complete it and move on to the next one.
The Catch Me A Big Fish sees us hunting down and catching a Lunker Bass. It can be found during chapter 4. So where can we find one of these Lunker Fish? How can we sell one? Well in the blue request note we are given a huge hint in the form of a picture. Making this one really simple and easy.
REQUEST: Catch Me A Big Fish (Sell a Lunker Bass)
REWARD: x4 Spinel
CHAPTER: Chapter 4
DESCRIPTION: Could someone catch the gigantic fish that lives in the lake for me? Fish oil has many uses, after all.
WHERE TO FIND THE LUNKER BASS?
The request for this one can be found in the Lakeside Settlement and after using the Insignia Key. Our task is to find a Lunker Bass fish. This fish is much larger than most of the other common fish. Not quite as big as the Del Lago though, of course.
You will find it within the nearby Lake and once you do manage to find it we will then need to use a harpoon and eliminate it. Basically catch it. We can throw a harpoon by using the L1 button and the R2 button to throw it. Once it has been slain we will then need to ride over towards it. Here we can pick it up and collect it. Warning though as it takes up quite a bit of space in the inventory.
Sell the Lunker Fish to the merchant in order to complete the request.
