In 1932, Disney received a special Academy Award for the creation of "Mickey Mouse", a series which switched to color in 1935 and soon launched spin-offs for supporting characters such as Donald Duck, Goofy, and Pluto. Pluto and Donald became standalone cartoons in 1937,[57] with Goofy following in 1939.[58] Of all Mickey's partners, Donald Duck, who first teamed up with Mickey in the 1934 cartoon, Orphan's Benefit, was arguably the most popular, going on to become Disney's second most successful cartoon character of all time.
