Snag-Stitches are metal-like enemies that first appear in Yoshi's Woolly World. They damage Yoshi on contact, and are found moving either left and right, up and down, or in a circled path. They cannot be defeated but they can be stunned by throwing a Yarn Ball at it in which they'll become a platform for the player to use for a short time before it breaks free.
Snag-Stitches only appear in the course, Snag-Stitch Mountain. Template:BoxTop
