Step 11:
Repeat step 10 on this end, see arrow.

Step 14:
Fold the tip of the model to the inside, see very short blue line.

Step 13:
Make an outside reverse fold over these lines.

Step 21:
Mountain-fold over this line, make the same fold (=valley-fold) on the other side of the leg. And make the same 2 folds on the other leg.

Step 19:
Press the model inwards on the place indicated by the arrow.

Step 20:
Mountain-fold over this line, make the same fold on the other side of the model.

Step 18:
Press the neck inwards, see arrow.

Step 17:
Mountain-fold over this line. And mountain-fold on the tip of the head, see arrow (fold just a tiny bit to the backside of the model).

Press the upper part of the leg flat between your fingers, by making a mountain-fold over this line.
Do the same on the other leg.

Step 28:
Pull the end indicated by the arrow upwards.

Step 25:
Valley-fold over the very short blue line at the left of the arrow.

Step 26:
Make an inside reverse fold over the short lines at the arrow (=valley-fold over the line in the middle and mountain-fold over the 2 other lines).

Step 24:
Fold the leg to the left on the place at the upper-arrow.
Then fold the leg to the right on the place indicated by the arrow below.

Step 23:
Open the leg on the place indicated by the arrow.
