How do you get the beauty scarf in Pokemon Mystery Dungeon?

Oh, dude, getting the beauty scarf in Pokemon Mystery Dungeon is like finding a shiny Charizard in the wild - it's rare! You can find it in the Joyous Tower dungeon, but good luck with that, it's like trying to get Pikachu to evolve into Raichu without a Thunder Stone. Happy hunting, my friend!
