Thank you very much my friends all i can say is she was very hard to find and i just got lucky, so far that the only way to unlock her i try other paths to see if she will appear but no luck, however when the 3 new nights come out next year there might be other paths to unlock her but for now that the only way.
Also a little note for night fox works that was very sneaky to hide her by doing some certain paths but i manage to find the right path to unlock her but tell me something has anyone else beside me figure out how to unlock "lexy the shark" in the discord server or am i the only one that figure it out ???
