this is a mind trick, the picture is made in such a way to give the illusion of multiple feet and legs... the еще Ты look at it, the less it makes sense, your brain tries and make sense of it, but it can't. But that's when Ты focus on it's legs.
go by how many feet there are, there can't be еще legs than feet, and there are 5 feet, so we can assume that it has 5 legs, it's a simple optical illusion really.
^it's just the shading on the picture, it's in the spots where the legs SHOULD be, because that it what your brain is used to seeing, BUT the feet are in a different area, your brain attempts to connect the two, and can't make sense of it, so it makes Ты see multiple legs. But instead of looking at the слон as a whole, just look at it's feet, on at a time, there are five feet, and five legs. Ты just need to dicpher the illusion
