Mega Yin-Yarn

Mega Yin-Yarn appeared in 2010 video game called Kirby's Epic Yarn. Mega Yin-Yarn is the transformed version of Yin-Yarn in Kirby's Epic Yarn. After Yin-Yarn's apparent defeat, his true identity is revealed to be knitting needles, which use the magic yarn that previously dropped from the yarn body they used as disguise to create this tank-like monstrosity. Kirby fights him in Tankbot form thanks to a metamortex dropped by Meta Knight.

Mega Yin-Yarn looks like a more menacing version of Yin-Yarn with an even more evil look on his face. He retains his hat, holds his two enlarged knitting needles in long lengths of red thread that act as his arms, and has two spiked wheels for feet. His moustache is slightly more jagged-looking and his body is spherical in shape.
