Probably the most popular of the non-regular Disney characters. Their names were Fifer Pig, Fiddler Pig and Practical Pig, although Practical Pig was the only one ever mentioned by name in any of the shorts. They were also the first of Disney's cartoon creations that he felt were imbued with actual personalities and character; a fact that was validated by their immense popularity during the Great Depression. (For more details, see the write up for the short in which they were introduced, 1933's "The Three Little Pigs.")
