Swimming Fish by Ng Boon Choon

Unlike most origami fish, this model will swim from side to side and looks very lifelike!

1 White side up, fold in half from top to bottom.

2 Crease and unfold through both layers.

3 Fold so the corner touches the circled point.

4 Make a crimp in the paper.

5 Fold so the circled points meet, crease and unfold.

6 Carefully, make a small precrease.

7 Form a point using three valley creases. The mountain forms as you flatten the flap. Refer to the next drawing for the shape.

8 Repeat steps 3–7 on the underside.

9 Lift up the lower half of the model.

10 Fold the corner to the circled point, and then unfold.

11 Fold the corner in to the previous crease, and then over again.

12 Fold the upper half behind.

13 Fold the right edge to the lower edge, crease and unfold.

14 Reverse the corner inside.

15 Precrease and sink the top corner inside. Fold both tail flaps over.

16 Pull out the inner flap so it lies on top dotted line.

17 Fold the lower point down with a valley on the dotted line.

18 Fold the tail flap behind along the existing crease.
