Need a fun little Halloween make that is cute, squishy, and beginner-friendly? This Frankenstein stress ball uses simple crochet rounds and playful bubble-stitch bolts for a character you’ll love to squeeze.
That little Frankenstein face is one of those crochet designs that feels especially satisfying once the details come together. The rounded shape is simple to build, while the green head, purple band, and tiny gray bolts give it enough character to make the finished piece feel much more special than a basic crocheted ball.
What I like about this crochet pattern is that the bubble stitch is the one technique that gives the design its personality without making the whole pattern complicated. Once the color changes and bubble stitches are understood, the rest is mostly straightforward shaping and stuffing. The result is a soft, squishable Halloween decoration that can also sit on a desk, be given as a seasonal gift, or simply become a fun little handmade companion.
Materials & Tools Needed
- Yarn:
- Green
- Black
- Gray
- Purple
- Crochet Hook: 4.5 mm
- Safety Eyes: 10 mm
- Fiberfill Stuffing
- Stitch Marker: Helpful for keeping track of rounds
- Yarn Needle: For finishing and closing

Finished Size & Customization Ideas
The finished Frankenstein is approximately 2–3 inches in diameter, depending on your yarn, hook, and tension.
You can easily change the look by using a darker or lighter green for the face, changing the purple band to another color, or adding small embroidered scars. If you want a larger or smaller version, changing the yarn weight and hook size will affect the finished size.
Helpful tip: Because this is meant to be squishy, avoid making the fabric too loose. A slightly firm fabric helps the stuffing stay contained and gives the finished piece a better rounded shape.

Step-by-Step Crochet Instructions
Frankenstein Base and Body
The body is worked in joined rounds, beginning with black yarn and gradually building the rounded shape before changing to green for the face.
Round 1: With black yarn, make a MR and work 6 sc into the ring; pull the ring tight. [6 sts]
Round 2: Work 1 inc in each st around. [12 sts]
Round 3: Work (1 sc, 1 inc) × 6 around. [18 sts]
Round 4: Work (2 sc, 1 inc) × 6 around. [24 sts]
Round 5: Work (3 sc, 1 inc) × 6 around. [30 sts]
Rounds 6–7: Work 1 sc in each st around for 2 rounds. [30 sts per round]
Changing to Green
When changing from black to green, make the color change during the final stitch of the previous round so the new color is ready for the next round. Keep the unused yarn ends controlled inside the work rather than leaving them loose on the outside.
Round 8: Change to green and work 1 sc in each st around. [30 sts]
Rounds 9–11: Continue with green, working 1 sc in each st around for 3 rounds. [30 sts per round]
Adding the Gray Bubble-Stitch Bolts
The two gray bolts are the most distinctive part of Frankenstein’s face. The bubble stitch creates the raised, rounded texture, so keeping your tension consistent will help both bolts look similar.
Round 12: With green, work 8 sc; change to gray and work 1 bubble stitch in the next st; change back to green and work 10 sc; change to gray and work 1 bubble stitch in the next st; change back to green and work 8 sc. [30 sts]
How to Make the Bubble Stitch
For each gray bubble, repeatedly work the partial stitch into the same stitch until you have 6 loops on the hook, then change back to green and pull the green yarn through all 6 loops to complete the raised stitch.
Teaching tip: Don’t pull the individual loops extremely tight. Leaving them slightly relaxed gives the bubble enough room to puff outward instead of disappearing into the fabric.
Rounds 13–14: With green, work 1 sc in each st around for 2 rounds. [30 sts per round]
Purple Band and Bottom Shaping
Round 15: Change to purple and work 1 sc in each st around. [30 sts]
Round 16: Work (3 sc, 1 dec) × 6 around. [24 sts]
Round 17: Work (2 sc, 1 dec) × 6 around. [18 sts]
At this point, attach the 10 mm safety eyes between Rounds 10 and 11, leaving approximately 4 stitches between them. Check the expression before securing the backs.
Round 18: Work (1 sc, 1 dec) × 6 around. [12 sts]
Round 19: Work 6 dec around. [6 sts]
Stuffing the Frankenstein
Before closing the final opening, fill the body firmly with fiberfill. Add small amounts at a time and distribute the stuffing evenly around the inside rather than pushing one large piece into the center.
Why this matters: If the stuffing is packed unevenly, the face can become lopsided and the finished shape may lose its rounded stress-ball appearance. Fill the sides first, then add enough stuffing to give the center a firm but squeezable feel.
Closing the Bottom
Cut the yarn, leaving a long enough tail for closing.
Thread the tail onto a yarn needle and weave it through the front loops of the remaining 6 stitches. Pull gently but firmly until the opening closes completely.
Secure the yarn with a knot, weave the remaining tail into the body, and trim the excess.
Finishing Touches
The basic shape is now complete, but a few small details can make Frankenstein instantly recognizable.
Add Facial Details
The safety eyes create the main expression, while the gray bubble stitches act as the classic Frankenstein bolts. For extra character, you can embroider small black scars or short stitched lines across the green section.
Keep the Bolts Raised
After finishing, check both gray bubbles. If one has flattened slightly, gently shape it from the inside with your fingers. Avoid pulling the surrounding stitches too tightly, as this can flatten the textured detail.
Easy Ways to Customize Your Frankenstein
- Use lime green for a brighter Halloween look.
- Try dark purple or black instead of the purple band.
- Embroider small scars across the forehead or cheeks.
- Use contrasting yarn for the eyes if you want a more cartoon-like expression.
- Change yarn weight and hook size to create a different finished size.
Final Check
Before trimming the last yarn ends, make sure:
- The body is evenly stuffed.
- The bottom opening is completely closed.
- Both safety eyes are firmly secured.
- The two gray bubble stitches are clearly raised.
- All yarn tails are woven securely inside.
Your Crochet Frankenstein Stress Ball is ready for Halloween! Its rounded shape makes it fun to squeeze, while the colorful Frankenstein details give it plenty of spooky-season personality. It can be displayed on a desk or shelf, added to a Halloween collection, or given as a small handmade gift.
