The Big Bad Wolf costumes changed a few times in the Disney parks.
In 1955, the first costume was on four legs.
In the 1960s, the Big Bad Wolf costume was on two legs and began to resemble his animated version, but he has brown fur, green overalls and a gray hat with a green stripe.
In the 1970s, the Big Bad Wolf costume has added toes to his feet and his gloves are nearly inside his furred arms.
Since the late-1970s and early 1980's, the current Big Bad Wolf reverted to the previous version, but with a blue hat instead of a gray one.
