Mickey Mouse universe

Mickey Mouse universe
In animation, Mickey's nephews first appear in the 1933 "Mickey Mouse" film "Giantland", although the film shows Mickey with as many as 14 nephews at the same time. The following year the nephews appear again in "Gulliver Mickey". The following film, "Mickey's Steam Roller", is the first to show Mickey with only two nephews, who can be presumed to be Morty and Ferdie, although they are unnamed in the film itself. This was two years after the twins debuted in the comic strip. Morty and Ferdie also make a cameo towards the end of 1938's "Boat Builders" and appear again in 1983's "Mickey's Christmas Carol" in speaking roles, albeit at different ages as one of the twins took on the role of Tiny Tim. In 1999 they make a cameo in the two part "Mickey Mouse Works" segment "Around the World in Eighty Days", which was used again in "Disney's House of Mouse".
