when Pretty Kitty asks you questions answer "Yes" or "No" there are naming easter eggs. They are: Sans Bendy Mettaton Golden Freddy Boris Undyne Foxy Alice Angel Papyrus Freddy Alphys Mangle Mike Joey Drew and Purple Guy When you say that you are purple guy she will ask "Which one?" and you will have to answer either "Springtrap" or "Purple Guy". HAVE FUN!!!
