What is the name of the Kirby game that features a yarn aesthetic?

The Kirby game with a yarn aesthetic is Kirby's Epic Yarn. It transforms Kirby and his surroundings into a crafted world made from yarn, fabric, thread, and other textile materials.

Released for the Wii in 2010, the game was developed by Good-Feel and published by Nintendo. Kirby is sent to Patch Land after encountering a magical tomato and must help Prince Fluff restore the land by collecting seven pieces of magic yarn and stopping Yin-Yarn.

The visual style also changes the gameplay. Kirby cannot inhale enemies or fly normally because his body has become yarn. Instead, he uses a yarn whip and transforms into objects such as a parachute, car, submarine, tank, or train. The game began as a project starring Prince Fluff before Nintendo repositioned it as a Kirby title.

A common mix-up is Yoshi's Woolly World, which also uses a yarn-inspired presentation but belongs to the Yoshi series. Kirby's Epic Yarn later received a Nintendo 3DS version called Kirby's Extra Epic Yarn.
