Trivia: Kirby's Epic Yarn
- Fan Nickname: The Maxim Tomatos in other Kirby games are being called "Metamatos" by fans, named after Yin-Yarn's fake one in this game.
- Hey, It's That Voice!: The narrator in the US version of the game is David Frederick White, aka General Pepper and Pigma in Star Fox 64.
- What Could Have Been: The game was originally pitched as a new IP, entitled "World of Fluff". The game would have been mostly the same, but with original enemies and starring Prince Fluff. Fearing it wouldn't sell, Nintendo decided to shift it to being a Kirby game, and to make Prince Fluff the supporting lead for the story and the Player 2 character.
