Morty and Ferdie Fieldmouse

Morty and Ferdie Fieldmouse (voiced by Kate Higgins as Morty and Tara Strong as Ferdie) are Mickey Mouse's twin nephews who first appeared in Floyd Gottfredson's Mickey Mouse Sunday comic strip continuity titled Mickey's Nephews (published in 1932). Since then, they have appeared in lots of comic strips, board books, and comic book stories starring Mickey Mouse and Pluto, but unlike Donald's nephews, they rarely show up in animation.
