This is how the The Three Little Pigs costumes have changed over the years in the parks.
In 1955, the first set of the costumes had the size of a grown up and had their heads, arms, and bodies covered with fur.
Then, the next set of costumes; they had sculpted heads and hooves.
And later on, they had larger heads and wider bodies.
In the 1960s the Three little Pigs had larger heads, wider bodies, and shorter arms.
1980's-present: The costumes of the Pigs,were used as alternates in parades, meet and greets, and the Tokyo Disneyland version of One Man's Dream.
The current Three Little Pigs costumes, first seen in 1989, look similar to the ones in the previous picture, but are a lot stouter.
