Loopy Pufferfish (Cá Nóc) Amigurumi Crochet Pattern

This amigurumi pufferfish pattern features an expressive body, textured detail, and playful color changes. Designed for charm and whimsy, each part - from the hat to the fins - brings bold character to this quirky creation. The pattern employs simple crochet techniques with engaging loop and popcorn details, making it an engaging project for any amigurumi enthusiast.

Pattern Basic Points

• Body and head are crocheted as a single sphere, using foundational amigurumi increases and decreases.
• Popcorn stitches and color changes in the middle rounds form the classic loopy, spotted texture associated with pufferfish.
• A mini hat is worked separately and fits snugly over the head, featuring back-and-forth flat rows and a decorative brim.
• The tail and fins use chains and textured stitches for dynamic shapes, while two simple magic ring eyes complete the fish's expressive face.
• All components are joined with straightforward sewing and assembly techniques using yarn tails.

Special Notes

• Work in continuous rounds - do not join unless otherwise specified. Use a stitch marker to keep track of the start of each round.
• Stuff the fish body as you progress, especially after the main body is closed so it holds shape.
• The popcorn stitch adds texture; you may substitute with a bobble stitch if preferred.
• Secure color changes by carrying non-working yarn along the inside to prevent holes.
• Use milk cotton yarn for a soft, sturdy finish and clear stitch definition.
