Finished Size & Customization Ideas
This frog is designed as a miniature, pocket-sized amigurumi. Its exact finished dimensions will depend on your yarn, tension, and assembly.
Ways to customize your frog:
- Make it a keychain: Securely attach a metal keychain ring or loop to the top of the head after assembly.
- Embroider the pupils: Replace the plastic eyes with embroidered French knots using black embroidery floss if you prefer a sewn facial detail. For items intended for babies or young children, avoid safety eyes and other small detachable parts, and follow age-appropriate toy-safety guidance.
- Change the colors: Try different shades of green or use another body color with the same white belly for a personalized frog.

How to Crochet the Frog Keychain
1. Make the Frog Body with Green Yarn
The body is worked in continuous rounds, starting with a magic ring. Use a stitch marker to identify the first stitch of each round and move it up as you go.
Round 1: Make a magic ring and work 6 single crochets into it. Place a stitch marker in the first stitch, then pull the yarn tail to close the ring. Total: 6 stitches.
Round 2: Work 2 single crochets into every stitch around. Mark the first stitch of the round. Total: 12 stitches.

Round 3: Repeat 1 single crochet in the next stitch, 1 increase in the following stitch six times. Total: 18 stitches.
Round 4: Repeat 1 single crochet in each of the next 2 stitches, 1 increase in the following stitch six times. Total: 24 stitches.
Rounds 5-9: Work 1 single crochet in every stitch around for five rounds. Keep the stitch count at 24 stitches per round. These rounds build the height of the frogβs body.
Round 10: Repeat 1 single crochet in each of the next 2 stitches, 1 decrease six times. Total: 18 stitches.

To make a decrease, insert your hook into the front loop of the next stitch and then into the front loop of the following stitch. Yarn over and pull through both front loops, then yarn over and pull through the remaining loops on your hook.
Round 11: Repeat 1 single crochet in the next stitch, 1 decrease six times. Total: 12 stitches.
Stuff the body: Add cotton stuffing through the remaining opening. Distribute it evenly and shape the body into a rounded form. Keep the opening accessible for the final round.
Round 12: Make 6 decreases around. Total: 6 stitches.
To close the body, make a slip stitch into the next stitch, chain 1, and cut the yarn, leaving a long tail. Thread the tail through your darning needle and pass it through the front loops of all 6 remaining stitches. Pull firmly until the opening closes. Insert the needle through the body a few times to secure the yarn, then trim the excess.

2. Make the Two Green Eye Circles
Make 2 small circles using green yarn. These circles create the bases for the frogβs pupils.
- Begin with a magic ring.
- Work 6 single crochets into the ring.
- Pull the yarn tail tightly to close the center.
- Cut the yarn, leaving a long tail for sewing, and fasten off.
Keep the sewing tails long enough to attach both circles securely to the body.

3. Add the Four Tiny Legs
The legs are made directly on the body, rather than crocheted separately. Before attaching them, use pins to check their placement.
- Position the top two legs around Round 6 and the bottom two around Round 10.
- Align the legs vertically with the eye circles so the frogβs face and body look balanced.
- Insert your hook vertically through the designated stitch and pull a new strand of green yarn through.
- Chain 2.
- Yarn over and insert the hook back into the same stitch space. Yarn over and pull through, giving you 3 loops on the hook.
- Yarn over and pull through all 3 loops.
- Chain 1 and cut the yarn.
- Tie the two yarn tails together securely, then hide them inside the body with your hook or darning needle.
Repeat these steps for all four legs. Check that each leg points outward and that the upper and lower pairs sit at similar heights on either side.

4. Crochet the White Belly
Use white yarn to make a small, flat circle for the frogβs belly.
Round 1: Start with a magic ring and work 6 single crochets into it. Pull the tail to close the center, then slip stitch into the first stitch to join the round.
Round 2: Chain 1, then work 2 single crochets into each of the 6 stitches around. Total: 12 stitches.
Slip stitch into the first stitch to join. Chain 1 and cut the yarn, leaving a short tail.
Before attaching the belly, flatten the circle gently and check that it sits neatly on the lower front of the frog. The white circle should be centered between the legs without covering their attachment points.

Assemble the Frog Keychain
5. Sew the Eye Circles onto the Body
Place the two green eye circles against Round 3 of the body and secure them temporarily with pins. Check their spacing from the front before sewing.
Thread the long tail of each eye circle onto your darning needle. Sew vertically through the stitches of the circle and into the body, securing each one firmly. Hide any remaining magic-ring tails inside the body.
6. Attach the Black Pupils
Apply a small dot of hot glue to the center of each green eye circle, then press one 7 mm black plastic safety eye into place.
Follow the safety-eye manufacturer’s instructions if the eyes are designed to lock into place with washers or other fittings. Do not rely on hot glue alone to secure safety eyes, especially on toys handled by children. Keep hot glue and small parts away from children while assembling the frog.

7. Attach the White Belly
Center the white circle on the lower front of the body, beneath the eyes and between the legs. Check its position from the front before attaching it.
Apply a thin layer of hot glue to the back of the white circle and press it carefully onto the body. Hold it in place until the adhesive sets according to its instructions. Avoid using excess glue, which may seep out around the edges.
If you prefer a stitched finish, you can sew the belly to the body using its yarn tail instead of gluing it.
8. Add the Keychain Loop
To turn the finished frog into a functional keychain, attach a metal ring or sturdy loop at the top of the head. Secure it through a strong, central section of the body so the weight of the keychain does not pull on a single loose strand.
Check the attachment by gently tugging the ring before using the keychain. Hide any remaining yarn ends inside the body and allow the adhesive to set fully before handling the finished frog.
Your Mini Frog Is Ready
Your little green frog now has its rounded body, four tiny legs, white belly, and black pupils. Check that the yarn ends are secure, the belly is firmly attached, and the keychain hardware cannot pull loose. With its small size and cheerful face, this frog makes a cute handmade accessory or a thoughtful little gift.
