Little Yellow Duck
Little Yellow Duck is a minor character, who's only appearance was in Ain't That Ducky (1945).
The Little Yellow Duck could be seen as a cry-baby, for throughout the majority of the film, he is seen crying at an object in a bag. During every attempt of Daffy and the hunter's to help out the kid, the Little Yellow Duck always respond with vulgar language.
The Little Yellow Duck is also very fond of his only piece of property: a brown bag. When Daffy and the hunter attempt to capture the bag to see why the yellow duck is crying, the Little Yellow Duck always ends up snatching it back (except at the final attempt, where it is revealed that the yellow duck is crying over a piece of paper that reads "The End.").
