Step-by-Step Instructions

The Hands (Make 2)

We begin by crocheting the fingers individually using blue yarn. Work in continuous rounds.

The Thumb

Rnd 1: 6 sc in mr (6)
Rnd 2-6: 6 sc (5 rounds total) (6)
Fasten off and leave a tail.

The Other 4 Fingers

Rnd 1: 6 sc in mr (6)
Rnd 2-7: 6 sc (6 rounds total) (6)
Fasten off for the first three fingers. Important: For the 4th finger, do not fasten off!

Joining the Fingers

Now, we join the fingers to form the hand. Work around the edges of the fingers: 3 sc around the 4th finger, 3 sc around the 3rd, 3 sc around the 2nd, 6 sc around the 1st (thumb), 3 sc around the 2nd, 3 sc around the 3rd, and 3 sc around the 4th (24).
Rnd 1-2: 24 sc (24)
Rnd 3: 9 sc, 3 sc together with the thumb, 12 sc (24)
Rnd 4: 9 sc, 3 sc around the thumb, 12 sc (24)
Rnd 5-6: 24 sc (24). Insert a thin 0.5mm wire structure shaped like a hand into the palm so it reaches every finger.
Rnd 7: (2 sc, 1 dec) * 18. Stuff the palm lightly; do not stuff the fingers.
Rnd 8: (1 sc, 1 dec) * 6 (12). Take a 7.8 inch piece of 2mm wire, connect it to the thin wire using masking tape, and insert it into the hand.
Rnd 9: (2 sc, 1 dec) * 3 (9)
Rnd 10-11: 9 sc (9). Mark the edge of the palm near the thumb; this marker will be used for assembly.
Rnd 12: 4 sc, 1 inc, 3 sc, 1 inc (11)
Rnd 13: 5 sc, 1 inc, 4 sc, 1 inc (13)
Rnd 14: 13 sc (13)

The feet are made of 4 toes each. Use blue yarn and work in continuous rounds.

The Toes

Rnd 1: 6 sc in mr (6)
Rnd 2-4: 6 sc (3 rounds) (6)
Fasten off for the first three toes. For the 4th toe, do not fasten off!
Join the toes: 3 sc around the 4th, 3 sc around the 3rd, 3 sc around the 2nd, 6 sc around the 1st, 3 sc around the 2nd, 3 sc around the 3rd, 3 sc around the 4th (24).

Assembly: Place the head on the wire, sew the helmet on, and attach the goggles and strap.

Finishing and Assembly

Now for the magic! It’s time to put all your hard work together.

Face Placement: Count 19 rows down from the top of the head. This is where the eyes go. Place the white eye pieces, leaving 2 stitches between them. Pin them with safety pins, add a little stuffing, and sew them to the face.
Eyelids: Sew the blue eyelids along the top edge of the white eyes.
Mouth: Pin the black felt piece to the face first, then pin the upper and lower lips. Ensure the lips are unfolded so the teeth point forward and don’t twist. Sew the sides of the lips together and sew the entire mouth assembly to the face from the back.
Eyes: Fit your plastic safety eyes into the white eye sockets. Remember: for this character, the right eye should be slightly smaller (13mm) than the left (15mm). Glue them into place once you are happy with the position.
Final Touches: Add the goggles to the helmet and attach the goggle strap. Don’t forget to sew the vest onto the body!

Tips for Success

Wire Safety: Always wrap the ends of your wire with masking tape or electrical tape to prevent them from poking through the crochet fabric.
Stitch Markers: Because amigurumi is worked in continuous rounds, using a stitch marker is essential to avoid losing your place.
Shading: For a professional look, use a little bit of brown eyeshadow or dry pastel to shade the elbows, knees, belly button, and brow area. This adds incredible depth to your toy!
Blocking: Steaming your accessories (like the vest and helmet straps) is the secret to making them look clean and well-shaped rather than curly or messy.
