1Mountain fold the diagonals and unfold.

2Mountain fold in half along one diagonal, then valley fold each corner up.

3Mountain fold as shown, using the edge as a guide, then valley fold back up to make a shallow pleat. Turn the model over and repeat.

4Mountain and valley fold as shown, then unfold. Open up the model and crimp fold on existing creases.

6Fold the right edge in on the diagonal. The paper at the folded corner will shift. Press this corner flat.

7Repeat step 6 on the other side of the tail.

8Repeat steps 4 to 7 on the opposite side. Note that the folding lines are closer to the end point than in step 4.

10Fold the bottom edge to the top crease.

11Repeat steps 9 and 10 on the opposite edge.

12Form legs by pleating as shown. Tip: Use tweezers for this. Grab the paper between tweezer jaws and twist the paper. It will form both folds.
