The ducks are minor characters in Oswald.
The ducks are water birds residing in Big City. They are often seen walking in a single-file line (with the ducklings following after their mother). The smallest duckling (whose plumage is noticeably lighter than the other ducks' feathers) becomes a good friend of Daisy after following her around for a day.
The ducks all have yellow feathers, black eyes, orange beaks and orange feet. The youngest duckling's feathers are a lighter yellow color.
The ducks appear in three episodes of Oswald. Their first appearance was in "The Polka Dot Umbrella." They later appear in "One More Marshmallow" and play a prominent role in "Daisy and the Duckling."
