How many legs does this elephant have?

Tricky, isn’t it?! This picture is an impossible picture that also contains some subjective contours, such as theKanizsa Triangle below: A white triangle (pointing down) can be seen in this figure even though no triangle isactually drawn. This effect is known as a subjective or illusory contour. The contour of the triangle is created by the shapes around it.

My guess is 5.How many feet did you get?
