I borrowed a DS cartridge from my cousin in 2015 or 2016; it didn't have a box for the game. I think it was on a box of another game; it's not modified in the slightest. That said, during 2022 or 2023, I think I found a secret cutscene in this game. I don't know the exact activation steps, but I remember it appeared after defeating the preevolution of my character (a feraligatr, to be exact) in a mission probably made in a wondermail generator. I don't remember how the exact cutscene was; I just remember that the main protagonist had a dialogue like "Mom?" with his partner, which led to a cutscene of the fully evolved version of my character hiding in a giant hole on the ground on a rainy day. I was awake during this; this couldn't be a dream. To be honest, it was a long time ago; I forgot the exact details. I think I wasn't fighting my character's pre-evolution but my partner's pre-evolution; either way, one of them just mentioned something about a mom, and I want to decipher what this is. I deleted that save file years ago and have never touched the game to this day. This happened to someone else?
