This piranha uses a zipper for a row of teeth! The mouth piece is separate so they can eat candy, or little fingers! Designed by Amanda Berry @fluffandfuzz, the piranha is knitted in acrylic DK yarns on single pointed needles (not in the round).  This pattern incorporates a three-needle bind off and Kitchener stitch grafting.
