>>41850959The way you get it in Gen 4 is even worse than Gen 3 because you're on a time limit. You have until the end of the day to search all 528 tiles in this lake before they all reset and you have to reset. Only 4 of them have a Feebas and other Pokemon besides Feebas can appear on a Feebas tile. It's entirely possible that you don't get a Feebas even after searching the entire lake and you would have to do it again.
