Knit in a circle (not spiral) single crochet.

Head and body:

1: 6
2: 6
increases = 12 3: (increase, 1) * 6 = 18
4: (increase, 2) * 6 = 24
5: (increase, 3) * 6 = 30
6: (increase, 4) * 6 = 36
7: (increase, 5) * 6 = 42
8: (increase, 6) * 6 = 48
9: (increase, 7) * 6 = 54
10: (increase, 8) * 6 = 60
11-15 : 60
16: (8, decrease) * 6 = 54
17: (7, decrease) * 6 = 48
18: (6, decrease) * 6 = 42
19: (5, decrease) * 6 = 36
20: (4 .decrease) * 6 = 30
21: (3.decrease) * 6 = 24
22: (2, decrease) * 6 = 18
23: (4.decrease) * 3 = 15
24: 15
25: (increase, 4) * 3 = 18
26: (increase, 2) * 6 = 24
27-28: 24
29: (increase, 3) * 6 = 30
30-31: 30
32: (increase, 4) * 6 = 36
33-34 : 36
35: 12, (increase, 1) * 6.12 = 42
36: 12, (increase, 2) * 6.12 = 48
37-39: 48
40: (6, decrease) * 6 = 42
41: (5 , decrease) * 6 = 36
42: (4, decrease) * 6 = 30
43: (3.decrease) * 6 = 24
44: (2, decrease) * 6 = 18
45: (1, decrease) * 6 = 12
46: Decreases before hole closure

Legs:

We knit 6 stitches in the 2nd loop
1: 3 loops from one, 3, 3 loops from one, 3 = 12
2: 3 increases, 3.3 increases, 3 = 18
3: (increase, 1) * 3.3 , (increase, 1) * 3.3 = 24
4: (increase, 2) * 3.3, (increase, 2) * 3.3 = 30
5: 30 behind the back wall)
6-7: 30
8: 15 , 6 decreases, 3 = 24
9: 15.3 decreases, 3 = 21 10:15
3 bars together, 3 = 18
11: (4, decrease) * 3 = 15
12-20: 15
21: decreases before closing

Pens:

1: 6
2: 6
increases = 12 3: (increase, 1) * 6 = 18
4: 18
5: (decrease, 4) * 5 = 15
6-8: 15
9-11: 4.7 double crochets, 4 = 15 form a bend
12-18: 15
19: decreases to close

Ears:

1: 6
2: 6 increments = 12
3: (increment 1) * 6 = 18
4-6: 18
Stuff during knitting as convenient.
I added granulate to the legs and belly.
