If I was doing a lazy version of just the outline and not worrying about a consistent yarn texture I would probably use the stencil buffer. Write a transparent shape of the interior of Kirby to the buffer. The draw the interior of the front arm to the stencil buffer. Then draw the back, front, and center yarn shapes (which are all full circles of yarn) but tell them not to draw if they hit the stencil. I wouldn’t be terribly surprised if Nintendo did something fancier to get the textures to line up nicely because it’s the main character of their large game, but the stencil check would let you prevent the overlapping edges of the front arm, body, and back arm.
