All the Yoshis on Craft Island are made of yarn! Don’t worry, Kamek hasn’t made them this way, it’s normal. However, Yarn Kamek turns all the Yarn Yoshis into Wonder Wools, hoping to knit a new castle for Yarn Baby Bowser. They missed two Yarn Yoshis, so it’s up to those two to travel all along Craft Island and return the Yoshis to their normal, woven forms.
