The LEGO Disney’s Baby Mickey theme was a subtheme of the LEGO Baby line that was released in 2000. It featured sets based on the Disney characters Mickey Mouse and Minnie Mouse as babies, along with their friends Pluto, Goofy, Donald Duck and Daisy Duck. The sets were designed for very young children and used DUPLO style parts. The theme was discontinued after 2000 and was succeeded by the LEGO Disney Mickey and Friends theme.
