How do you fold the fifth pig illusion?

To fold the fifth pig illusion, start with a square piece of paper and fold it diagonally to create a triangle. Then, fold the top corners of the triangle down to meet the bottom corner, forming a smaller triangle. Next, fold the outer edges of this smaller triangle inward to form the pig's ears. Finally, adjust and crease the folds to reveal the illusion of the fifth pig when viewed from the correct angle.
