Step 1:
Prefold over these 2 lines

Step 6:
Make a mountain-fold over this line

Step 5:
Make a valley-fold over these 2 lines.

Step 2:
Prefold over these lines.

Step 4:
And make another inside reverse fold on the edges you've just made (=mountain-fold over the 2 short lines and a valley-fold over the 4 longer lines)

Step 3:
Make an inside reverse fold over these 2 sets of lines. (=mountain-fold over the 2 short lines and a valley-fold over the 4 longer lines)

Step 10:
Make a valley-fold over these 2 lines.

Step 8:
Make another inside reverse fold on the edge you've made in step 7 Do this by making a mountain-fold over the short line in the middle and a valley-fold over the 2 longer lines.

Step 9:
Now the model looks like this

Step 7:
Make an inside reverse fold over the 3 black lines. A valley-fold over the red line is almost automatically made when you are doing this.

Step 16:
Fold the triangular flap downwards by making a valley-fold over the black line.

Step 15:
Press the edges flat from above, see arrows.

Step 12:
Make a valley-fold over these 2 lines.

Step 11:
Hold the model between 2 fingers at the place indicated by the yellow arrows.  Then press this edge flat from above with your other hand, see orange arrow

Step 14:
Fold the edge indicated by the arrow upwards by making a valley-fold over the black line.

Step 13:
Unfold the folds of step 12

Step 21:
Make an inside reverse fold over these lines. (=mountain-fold over the line below + valley-fold on the same place at the layer below and a valley-fold over the upper line)

Step 19:
Make an inside reverse fold over these 3 lines (=valley-fold over the short line in the middle and a mountain-fold over the 2 longer lines). Do the same on the other side of the neck.

Step 20:
Now the model looks like this.

Step 18:
Fold the corner indicated by the arrow to the right by making a valley-fold over the black line. Do the same as above on the other side of the body

Step 17:
Now the model looks like this

Step 22:
Press the tip indicated by the arrow downwards by making a mountain-fold over the short black line.

Step 23:
Press the legs flat from aside, see arrows. Do the same with the legs on the other side.
