The entire pattern is worked in continuous rounds.

Back side

Using yellow then dark brown yarn and 3.75mm hook.

sl on hook, ch x10, turn, work into 2nd st from hook, and work all the way around the chains.

R1: (sc x8, 3sc) x2 [22]
R2: (sc x9, 3sc, sc) x2 [26]

R3: (sc x9, inc x3, sc) x2 [32]

R4: (sc x9, (inc, sc) x3, sc) x2 [38]

Switch to dark brown.

R5: sc x5, hdc x4, (2hdc, hdc x2) x3, hdc x5, sc x5, (inc, sc x2) x3, sc [44]

R6: sc x4, hdc x5, (hdc x3, 2hdc) x3, hdc x6, sc x4, (sc x3, inc) x3, sc [50]

R7: sc x3, hdc x6, (hdc x4, 2hdc) x3, hdc x7, sc x3, (sc x4, inc) x3, sc  [56]

Finish off.

Front side

We are essentially doing the same stitches as the back side so we end up with the same shape, there are just more colour changes for this side.

Using light brown then yellow then dark brown yarn and 3.75mm hook.

With the colour changes in the chains, it's really easy to add or miss stitches, count each colour carefully!

sl on hook, ch x5, ch x5, turn, then starting in R1, work into 2nd st from hook.

R1: sc x4, sc x4, 3sc, sc x4, sc x4, 3sc [22]
R2: sc x4, sc x5, 3sc, sc x10, 3sc, sc [26]

Finish off yellow.

R3: (sc x9, inc x3, sc) x2 [32]

R4: (sc x9, (inc, sc) x3, sc) x2 [38]

R5: sc x5, hdc x4, (2hdc, hdc x2) x3, hdc x5, sc x5, (inc, sc x2) x3, sc [44]

R6: sc x4, hdc x5, (hdc x3, 2hdc) x3, hdc x6, sc x4, (sc x3, inc) x3, sc [50]

R7: sc x3, hdc x6, (hdc x4, 2hdc) x3, hdc x6, sc x4, (sc x4, inc) x3, sc  [56]

Do not cut dark brown yarn. We will finish all the details for each side before crocheting both sides together.

Mouth (make 2)

Using gray yarn and 3.75 mm hook.

R1: sc x3 in mr, ch, turn [3]
R2: inc x3 [6]

Leave a long tail for sewing

Hold the front side of the body so that the wider end is at the bottom. Sew the bottom mouth piece between R4 and R5 in the center. Then sew the other mouth piece above.

We will now be be connecting the back side with the front side. Place the 2 wrong sides facing each other (the sides with all the ends).

On the Back side, you can count 3 st to the left of the light brown st, that's where the first st of R8 will go into.

Make sure you work through all 4 loops in R8 (both loops of each Side).

If you are making the sturdier coaster, just ignore the note above.

Using the dark brown and light brown yarn and 3.75mm hook.

Continuing from the front side where we left off after R7. 

R8: sc x2, hdc x7, (2hdc, hdc x5) x3, hdc x7, sc x3, (inc, sc x5) x3, sc  [64]

In the next round, we will be making the fins and the tail using short rows. To make it easier to read, I will use the small r's to indicate rows when necessary. Each row will start or end with a sc on the body depending on the direction.

R9: sl x5, 

[Fins 1]

r1: sc (on body), ch x7, turn (work down ch in 2nd st from hook)

r2: hdc x3, sc x2, sl, sc (on body)

r3: sc (on body), turn, sc x7 (on ch, last st will be in the loop at the tip), ch, turn (work down ch in 2nd st from hook)

r4: hdc x3, sc x4, sc (on body)
Make sure you pass the light brown yarn under the stitches on the body until you use the light brown yarn again in r7.

r5: sc (on body), ch x3, turn (work down ch in 2nd st from hook)

r6: hdc x2, sc (on body)

r7: sc (on body), sc x3 (on ch, last st will be in the loop at the tip), ch, turn (work down ch in 2nd st from hook)

r8: hdc x2, sc, sc (on body)

on body: sl x16, 

[Fins 2]

r1: sc (on body), ch x3, turn (work down ch in 2nd st from hook)

r2: 2hdc, sc, sc (on body)

Make sure you pass the light brown yarn under the stitches on the body until you use the light brown yarn again in r5.

r3: sc (on body), turn, hdc x2 (on ch), ch, turn, 

r4: sk, sc, sc (on body)

r5: sc (on body), ch x8, turn (work down ch in 2nd st from hook)

r6: hdc x3, sc x4, sc (on body)

r7: sc (on body), turn, sc x6 (on ch), ch, turn (work down ch in 2nd st from hook)

r8: sk, hdc x3, sc x2, sc (on body)

on body: sl x9, 

[Tail]

r1: sc x13, ch, turn

r2: hdc x13, ch, turn

r3: sk, sc x11, sl 

Skip the rest of the stitches on the body. Finish off any loose tails, cut them a little shorter and hide them inside the body. We are done!!

The entire pattern is worked in continuous rounds.

Back side

Using green then black, (and a little white) yarn and 3.75mm hook.

sl on hook, ch x10, turn, work into 2nd st from hook, and work all the way around the chains.

R1: (sc x8, 3sc) x2 [22]
R2: (sc x9, 3sc, sc) x2 [26]

R3: (sc x9, inc x3, sc) x2 [32]

R4: (sc x9, (inc, sc) x3, sc) x2 [38]

Switch to black.

R5: sc x5, hdc x4, (2hdc, hdc x2) x3, hdc x5, sc x5, (inc, sc x2) x3, sc [44]

R6: sc x4, hdc x5, (hdc x3, 2hdc) x3, hdc x6, sc x4, (sc x3, inc) x3, sc [50]

There are some stitches in white in the next round.

R7: sc x3, hdc x6, (hdc x4, 2hdc) x3, hdc x7, sc x3, inc, sc x4, inc, sc x4, inc, sc x4, sc  [56]

Finish off.

Tester tip! Steam block this piece now if you want it to lay perfectly flat at the end.

Front side

We are essentially doing the same stitches as the back side so we end up with the same shape, there are just more colour changes for this side.

Using gray and green yarn and 3.75mm hook.

With gray yarn, sl on hook, ch x10, turn, work into 2nd st from hook, and work all the way around the chains.

R1: sc x7, sc, 3sc, sc x8, [sc, sc, sc] [22]
R2: sc x7, sc x2, 3sc, sc x2, sc x2, sc x6, 3sc, sc [26]

R3: sc x8, sc, [sc, sc], inc x2, sc x2, sc x2, sc x6, sc, inc x3 [32]

R4: sc x9, inc, sc x2, inc x2, sc x3, sc x2, sc x5, inc, sc, (inc, sc) x2, sc x2 [38]

R5: sc x5, hdc x4, 2hdc, hdc, hdc, 2hdc, hdc x2, 2hdc, hdc x4, hdc x3, sc x2, sc x4, inc, sc x2, inc, sc x2, inc, sc x2 [44]

R7: sc x3, hdc x6, hdc x3, (2hdc, hdc x4) x3, hdc x2, hdc, (sc x4, inc) x3, sc x5 [56]

It is easier to not cut the gray yarn until we switch to black in the last assembly section. We will finish all the details for each side before crocheting both sides together.

Tester tip! Steam block this piece now if you want it to lay perfectly flat at the end.

Mouth (make 2)

Make 1 in white yarn and 1 in red yarn.

Using 3.75 mm hook.

R1: sc x3 in mr, ch, turn [3]
R2: inc x3 [6]

Leave a long tail for sewing

Hold the front side of the body so that the wider end is at the bottom. Sew the white mouth piece between R4 and R5 in the center , this will be the bottom of the mouth. Then sew the red piece above.

Needle Felting Eyes

On each side of the mouth, pin a circle (diameter=1.4cm) smaller than the mouth. 

Using white wool, needle felt the circle for the eyes, then add a small black dot near the top of the eye for the pupil.

Optional: Use green to fix the green patches so it looks more like a bird footprint shape. You can also just use the yarn to go over the edges.
