Roscoe the Rat Crochet Amigurumi Pattern: Your New Favorite Fuzzy Friend

There is something undeniably charming about a well-made amigurumi rat. Maybe it is the tiny ears, the long skinny tail, or those little paws that look like they are perpetually up to something mischievous. Whatever the reason, rats have quietly become one of the most beloved subjects in the amigurumi community, and Roscoe the Rat is here to prove exactly why. This pattern is designed for intermediate crocheters who want a project that feels rewarding without being overwhelming, and the finished result is a soft, poseable little companion that genuinely looks like he has a personality.

Whether you are making Roscoe for yourself, gifting him to a rat lover in your life, or adding him to a collection of handmade animals, this pattern will walk you through every stitch, every shaping detail, and every finishing touch. By the time you are done, you will have a little brown rat who looks ready to steal a cracker off your kitchen counter.

What Makes Roscoe Special

Before we get into the yarn and hook specifications, it is worth talking about what sets this particular amigurumi rat pattern apart from others you might have tried.

Roscoe is designed with realistic proportions in mind. A lot of amigurumi rats end up looking more like round mouse blobs than actual rats, which is adorable in its own way but misses the distinctive ratty silhouette that makes rats so endearing. Roscoe has a longer, tapered body, a slightly elongated snout, large rounded ears that sit wide on his head, and a tail made with a simple but effective technique that gives it a satisfying, slightly curved shape.

He is also designed to sit upright on his haunches, with his little front paws held up in front of him, which is one of the most iconic rat poses and one that any rat owner will immediately recognize. If you have ever watched a pet rat sit up to eat something from its paws, you know exactly the look we are going for.

The colorway in the main pattern is a warm brown with a slightly lighter underbelly, which gives Roscoe a realistic two-tone look without requiring complex colorwork. However, the notes at the end of this post will give you guidance on adapting the pattern for black, grey, cream, or even hooded-rat colorings.

Materials You Will Need

Getting your materials together before you start is always a good idea, especially with amigurumi, where stopping mid-project to hunt down the right safety eyes can break your momentum.

For the main pattern you will need a 3.5mm crochet hook, which is the sweet spot for amigurumi work — tight enough to prevent stuffing from showing through but not so tight that your hands cramp up after an hour. If you tend to crochet loosely, go down to a 3.0mm. If you crochet tightly, stick with the 3.5mm and make sure your tension is relaxed.

For yarn, choose a DK weight (also called light worsted or 8-ply) in the following colors: a warm medium brown for the body and head, a light cream or off-white for the underbelly and inner ears, and a pale pink or dusty rose for the nose detail. You will not need much of any of these — for most crafters, the brown body yarn uses up roughly 100 to 120 yards, the cream uses about 30 yards, and the pink is just a few yards for the nose. This makes Roscoe a great stash-buster project.

You will also need polyester fiberfill stuffing, a yarn needle for sewing parts together and weaving in ends, two 9mm black safety eyes (or 10mm if you prefer a slightly wider-eyed look), wire armature or pipe cleaners if you want a poseable version, stitch markers, and a pair of scissors.

Optional but highly recommended: a small amount of craft wire for the tail, which gives it that satisfying gentle curve. If you prefer a softer tail that is safe for young children, you can skip the wire entirely and the pattern notes will tell you how to adjust.

Gauge and Sizing

With a 3.5mm hook and DK weight yarn, your gauge should be approximately 18 stitches and 20 rows to a 10cm by 10cm square worked in single crochet. This will produce a finished Roscoe that is approximately 18cm tall when seated (about 7 inches), with a tail length of around 14cm (5.5 inches).

If you want a larger Roscoe, switch to worsted weight yarn with a 4.0mm or 4.5mm hook. The stitch counts stay exactly the same, and your finished rat will be closer to 23 to 25cm tall — a chunkier, more huggable version that still has all the same charm.

Pattern Abbreviations

This pattern uses standard US crochet terminology throughout.

MR means magic ring. Ch means chain. Sl st means slip stitch. Sc means single crochet. Inc means increase, which is two single crochets worked into the same stitch. Dec means invisible decrease, which is worked by inserting your hook through the front loops only of the next two stitches before completing the decrease. FLO means front loops only. BLO means back loops only. Rnd means round.

The Pattern: Let’s Build Roscoe

Head

Start with your brown yarn.

Rnd 1: MR, 6 sc into ring. (6)

Rnd 2: Inc in each st around. (12)

Rnd 3: (Sc 1, inc) repeat around. (18)

Rnd 4: (Sc 2, inc) repeat around. (24)

Rnd 5: (Sc 3, inc) repeat around. (30)

Rnd 6: (Sc 4, inc) repeat around. (36)

Rnd 7: (Sc 5, inc) repeat around. (42)

Rnds 8 to 12: Sc around. (42)

Now we shape the snout. This is what gives Roscoe his distinctly rat-like face rather than a generic round head.

Rnd 13: Sc 16, (sc 2, inc) 3 times, sc 17. (45)

Rnd 14: Sc 16, (sc 3, inc) 3 times, sc 17. (48)

Rnd 15: Sc around. (48)

Rnd 16: Sc 16, (sc 3, dec) 3 times, sc 17. (45)

Rnd 17: Sc 16, (sc 2, dec) 3 times, sc 17. (42)

Place your safety eyes between rounds 9 and 10, approximately 12 stitches apart. The snout shaping rounds will be centered below and slightly forward of the eyes. This is a good moment to take a step back and look at the head from the front to make sure the placement feels right to you before locking in the safety eyes.

Rnd 18: (Sc 5, dec) repeat around. (36)

Rnd 19: (Sc 4, dec) repeat around. (30)

Begin stuffing the head firmly at this point. You want it to hold its shape well, so don’t be shy with the fiberfill.

Rnd 20: (Sc 3, dec) repeat around. (24)

Rnd 21: (Sc 2, dec) repeat around. (18)

Rnd 22: (Sc 1, dec) repeat around. (12)

Rnd 23: Dec around. (6)

Fasten off and close the gap with your yarn needle. Weave in ends.

Body

The body is worked separately and then attached to the head. This approach gives you more control over the stuffing and the overall shape.

Start with your brown yarn.

Rnd 1: MR, 6 sc. (6)

Rnd 2: Inc in each st around. (12)

Rnd 3: (Sc 1, inc) repeat around. (18)

Rnd 4: (Sc 2, inc) repeat around. (24)

Rnd 5: (Sc 3, inc) repeat around. (30)

Rnd 6: (Sc 4, inc) repeat around. (36)

Rnds 7 to 10: Sc around. (36)

Now switch to your cream yarn to work the underbelly panel. If you prefer to avoid color changes, you can embroider the underbelly detail after the fact or simply make Roscoe all one color, which also looks great.

To create the underbelly, flatten the body piece and identify the center front stitches. You will work the cream section across the center 12 stitches of the front each round, carrying the brown yarn loosely across the back, or simply dropping it and picking it back up each round.

Rnds 11 to 18: Continue in sc, working cream yarn across the center 12 front stitches and brown everywhere else. (36)

Rnd 19: (Sc 4, dec) repeat around. (30)

Rnd 20: Sc around. (30)

Rnd 21: (Sc 3, dec) repeat around. (24)

Rnd 22: Sc around. (24)

At this point, stuff the body firmly, making sure to tuck a good amount of fiberfill into the lower rounded section to maintain the plump, well-fed rat silhouette.

Rnd 23: (Sc 2, dec) repeat around. (18)

Do not fasten off yet. Use the remaining yarn tail to sew the body to the head. The neck join should sit at the flattened bottom of the head, and you want the snout pointing slightly upward and forward rather than straight ahead, which gives Roscoe a more alert, curious expression.

Ears

Make two in brown and two in cream.

For each ear piece, make a magic ring and work 8 sc into it. Fasten off with a yarn tail for sewing.

Hold one brown piece and one cream piece together with wrong sides facing and whip stitch around the edges, leaving a small gap to push in a tiny pinch of stuffing if you want slightly rounded ears, then close. Attach the cream side facing forward. Sew the ears to the top of the head at approximately rounds 5 to 6, spaced wide apart, roughly 8 stitches from the center top of the head on each side.

For slightly larger, more realistic ears, work the magic ring with 10 sc instead of 8, and add a second round of (sc 1, inc) for a total of 15 stitches before fastening off.

Arms

Make two, starting with brown yarn.

Rnd 1: MR, 5 sc. (5)

Rnd 2: Inc in each st around. (10)

Rnds 3 to 4: Sc around. (10)

Switch to cream yarn for the paw.

Rnds 5 to 7: Sc around. (10)

Rnd 8: Dec, sc 8. (9)

Rnd 9: Dec, sc 7. (8)

Leave the bottom open, stuff lightly, and flatten slightly before sewing to the sides of the body at rounds 4 to 5, with the paws pointing forward and slightly upward to achieve that classic “holding something” rat pose.

Legs and Feet

Make two.

Start with brown yarn.

Rnd 1: MR, 6 sc. (6)

Rnd 2: Inc in each st around. (12)

Rnd 3: (Sc 1, inc) repeat around. (18)

Rnd 4: Sc around. (18)

Rnd 5: Sc 6, (dec) 3 times, sc 6. (15)

Rnd 6: Sc 5, (dec) 2 times, sc 6. (13)

Rnds 7 to 11: Sc around. (13)

Stuff the foot firmly and the leg lightly. Flatten and sew to the bottom front sides of the body, angled slightly outward so that Roscoe sits stably on his haunches without tipping forward.

Tail

For the wire version: cut a piece of craft wire approximately 18cm long. Using your pink or cream yarn, work a very tight chain of approximately 60 stitches. Thread the wire through the chain carefully, fold the wire ends over so they are not sharp, and sew the tail to the back base of the body.

For the no-wire version: ch 60, sl st back along the chain to create a rounder, more textured tail. Sew to the base of the body.

Gently bend the tail into a soft S-curve for the most realistic look.

Nose

Using your pink yarn and a yarn needle, embroider a small triangular nose onto the tip of the snout using satin stitch. Three to four long stitches across and two or three in the other direction will give you a clean, neat nose. You can also add a tiny vertical stitch downward from the center of the nose for an optional mouse-like whisker line.

For whiskers, thread a length of white embroidery floss through the snout area and trim to your desired length. Many crocheters use monofilament fishing line for whiskers as it holds its shape beautifully, but stiff embroidery floss works well too.

Finishing Touches and Styling Ideas

Once all your pieces are assembled and your ends are woven in, take a moment to squeeze and shape Roscoe into his final pose. The beauty of fiberfill stuffing is that it has some give, so you can pinch the snout slightly to narrow it, nudge the ears forward or back, and adjust the angle of the legs until everything looks just right.

If you made the poseable wire version, now is the time to bend the arms and tail into position. Try posing Roscoe with his paws up close to his chest, or extend one arm out as if he is reaching for something.

For a finishing touch that really elevates the final look, consider adding a small embroidered belly button just above the underbelly seam, or a few sparse embroidered dots on each side of the snout to suggest whisker roots. These tiny details make a big difference in how lifelike and characterful Roscoe looks.

Color Variations to Try

The warm brown version of Roscoe is the main pattern colorway, but rats come in so many beautiful varieties that it would be a shame not to explore the options.

For a black Roscoe, substitute black yarn for all the brown sections and keep the cream underbelly. This creates a gorgeous hooded-rat effect if you also work the top of the head in black and transition to cream about halfway down the body.

For an agouti or wild-type rat, use a heathered brown yarn with flecks of tan or grey, which mimics the multi-toned coat of wild rats beautifully.

For an albino or pink-eyed white rat, use white or pale cream yarn throughout, swap the black safety eyes for pink or red ones, and use pale blush pink for the nose and ears.

For a blue or lilac rat (popular fancy rat colors), use a cool grey or dusty lavender yarn, which crochets up into an absolutely stunning finished rat.

Care Instructions for Your Finished Roscoe

Because Roscoe is likely to be loved, handled, and possibly dragged around by small children or equally enthusiastic adults, it is worth knowing how to keep him looking his best.

Hand washing in cool water with a gentle detergent is the safest option. Squeeze out excess water without wringing, reshape while damp, and allow to air dry flat. Most acrylic DK yarns hold up well to gentle machine washing on a delicate cycle in a mesh laundry bag if hand washing is not convenient, but always check your specific yarn’s care label first.

Avoid high heat, which can distort the safety eyes and cause acrylic fibers to mat or pill.

A Few Notes for Beginners

If this is one of your earlier amigurumi projects, a few pointers will make the process much smoother.

Working in a continuous spiral rather than joined rounds is standard for amigurumi, so use a stitch marker to track the beginning of each round and remember to move it up as you go. The invisible decrease is worth learning if you haven’t already — it creates a much neater, less visible decrease than a standard sc2tog, which matters a lot in tight-stuffed amigurumi.

When sewing pieces together, use the yarn tail from the piece you are attaching and a blunt yarn needle. Mattress
