— Yin-Yarn in Kirby's Epic Yarn and Kirby's Extra Epic Yarn
He separates his home world of Patch Land into seven pieces by stealing the Magic Yarn and one of the Magic Socks. Using these artifacts, Yin-Yarn travels to Dream Land, where he slowly begins turning its citizens and landscape into yarn and fabric.
Seemingly unaware of the rumors concerning Yin-Yarn, Kirby spots an odd-looking Maxim Tomato on top of a bush and starts to inhale it. Yin-Yarn appears from behind the bush, making an unsuccessful attempt to stop Kirby from eating the tomato on his hat. Angered by the loss of his magic Metamato, Yin-Yarn banishes Kirby to Patch Land, where Kirby is left to help retrieve the Magic Yarn with Prince Fluff. In Kirby's absence, Yin-Yarn continues to take control of Dream Land by sending a brainwashed King Dedede and Meta Knight to Patch Land in an attempt to stop Kirby. With Dedede and Meta Knight gone, there is no one to stand in the way of Yin-Yarn taking complete control over Dream Land–even if he doesn't have an idea what he'll do with it once he has total power.
During the final battle with him, it is revealed that "Yin-Yarn" is actually a pair of sentient knitting needle brothers. The two of them are eventually defeated by Kirby, who returns to Dream Land after recovering all seven pieces of the Magic Yarn and using Prince Fluff's Magic Sock to return home.
The events of the final battle strongly imply Yin-Yarn's true identity as the needles themselves, but it is only explicitly mentioned in the Japanese version.

— Patch Plaza description
Like all natives of Patch Land, Yin-Yarn appears to be made entirely of fabric and yarn. He wears a green sombrero, purple sunglasses and an orange poncho with intertwining green and red stripes. He has a black mustache and an orange button for a nose. His true bodies are the two large wooden knitting needles he carries at all time, who bear a passing resemblance to maracas. The two unnamed needles are visually distinct from one another: the right left needle has two horns, purple eyes and a scowl, while the right one has one horn, yellow eyes, and a neutral expression.

— Patch Plaza description of Mega Yin-Yarn
Also see the "vs. Mega Yin-Yarn" section.
Yin-Yarn's second battle form continues the tradition of circular Kirby bosses. Mega Yin-Yarn is slightly larger than the Tankbot. He retains the green sombrero, but his body is now similar to Kirby's: a head attached to yarn-thin arms and spiked wheels for feet. His facial features are broadened, including his sunglasses, his nose, his mustache, and the near-present smile that could otherwise be mistaken for the top of his poncho. His knitting needles have also enlarged.
The description for Mega Yin-Yarn states that Yin-Yarn used the Metamato's power to transform into his final form. However, going from the cutscene itself, it would appear that Yin-Yarn actually used the Magic Yarn to do that.
- An original dot sprite of Yin-Yarn appears as a Keychain in Kirby: Triple Deluxe.
- Yin-Yarn appears in the Celebration Picture: "Bad Boss Brothers" in Kirby Star Allies.
- Both versions of Yin-Yarn's battle background music are renditions of the regular boss theme from Kirby 64: The Crystal Shards. Unlike the other classic covers in this game, neither of these versions are acoustic; instead, they sound similar to how music is typically rendered in other Kirby games. This was done on purpose by composer Jun Ishikawa, as he wanted to surprise players in the final battle.
- Yin-Yarn's plot is very similar to that of Drawcia from Kirby: Canvas Curse. Both invade Dream Land, changing its landscape so that it resembles the landscape of their home worlds, and place a curse on Kirby that deprives him of his conventional means of attack.
- The first part of Yin-Yarn's Japanese name (アミーボ・アモーレ) is the same as amiibo despite their different name origins.
Flawless fight with Yin-Yarn.
