Crochet Green Monster Pattern (Easy Amigurumi Halloween Monster)

This friendly round-headed monster is an original, cartoonish design — big googly eyes, a wide stitched grin, and a single fuzzy horn, built for cuteness rather than scares.

Materials

• Green worsted weight yarn (about 40g)
• Small amount of black yarn for facial details
• Small amount of white or cream yarn for the horn
• 3.5mm crochet hook
• Fiberfill stuffing
• Two large safety eyes (different sizes for a fun, googly look)
• Yarn needle

Abbreviations

• MR — magic ring
• sc — single crochet
• inc — increase
• dec — invisible decrease
• st(s) — stitch(es)

Head and Body (worked as one piece)

1. MR, 6 sc in ring (6)

5. (3 sc, inc) around (30) 6–16. sc around, no increase (30) — 11 rounds

Attach the two safety eyes between rounds 7-8, spaced unevenly (one slightly higher than the other) for a playful, googly-eyed look.

17. (3 sc, dec) around (24)
18. (2 sc, dec) around (18)

Stuff firmly.

19. (1 sc, dec) around (12)

Fasten off, leaving a tail. Weave through remaining stitches and cinch closed.

Horn

With white or cream yarn:

1. MR, 5 sc in ring (5) 2-4. sc around (5) — 3 rounds

Fasten off, leaving a tail. Lightly stuff and sew to the top of the head, slightly off-center.

Facial Details

Embroider a wide, curved stitched mouth in black yarn, adding a couple of small triangular teeth peeking out for extra character.

Finishing

Weave in all ends. Optionally brush the body gently with a wire pet brush for a soft, fuzzy monster texture.

Tip: mismatched eye sizes and slightly asymmetrical features make this monster read as friendly and silly rather than symmetrical and serious — lean into the wonkiness.
