Doki Doki Literature Club Plus! (US)

If you go to the “Metaverse” fake desktop (by exiting DDLC in-game, NOT exiting to your xbox dashboard), you can open a folder marked “files”, then a folder marked “game”, then a file marked “poemwords.txt”. This will give you a list of Sayori's, Natsuki's and Yuri's favourite words to use in poems. Exclusively use words from the appropriate list to write a “perfect” poem.

Natsuki (alphabetically):
anger, anime,
blanket, boop, bouncy, bubbles, bunny,
candy, cheeks, chocolate, clouds, cute,
doki-doki,
email,
fantasy, fluffy,
games, giggle,
hair, headphones, heartbeat, hop,
jump, jumpy,
kawaii, kiss, kitty,
lipstick, lollipop,
marshmallow, melody, milk, mouse,
nibble, nightgown,
papa, parfait, peace, pink, playground, poof, pout, puppy, pure,
ribbon,
shiny, shopping, skipping, skirt, socks, spinning, sticky, strawberry, sugar, summer, swimsuit,
twirl,
valentine, vanilla,
waterfall, whisper, whistle

An extra note regarding Natsuki's word list: Natsuki has the shortest list of words, and the words available on each page of the minigame are random. It took me three tries to get this Achievement because, sometimes, you'll just get a page with none of Natsuki's words on it. Be prepared to reload a save.
