The title is a play on the 1950 film Father of the Bride and its 1991 and 1995 remakes.
A hungry Sylvester tries to find breakfast. He sees a feather, and realizes when there's feathers and birds, there's breakfast. He walks up and snatches a sparrow egg in a nest. He thinks about what he can make with the egg, but before he can eat it for breakfast however, a little bird hatches out and calls him "Mama." He realizes that his breakfast is talking but still eats the bird. However, the bird talks inside of Sylvester's mouth and keeps calling Sylvester his mama. Despite his attempts to make the bird leave, the bird just keeps following him. At one point, Sylvester tells the bird to not to call him "Mama", but the bird calls him "Papa." However, Sylvester suddenly warms to the idea of being a father and instead of eating it again, he protects the bird throughout a series of near-disasters.
He first sees the bird dangling on a telephone line and walks up to it. The telephone line pulls down, and the bird walks off, launching Sylvester to a construction site to be slammed into an I-beam and nearly get threatened to be smashed by an anvil. The bird walks into the construction site and it crawls into a bulldog's mouth. Sylvester fishes out the bird, but the bulldog manages to reel in Sylvester and attack him. The bird walks into a railroad track and walks up into a train. Sylvester follows, and is slammed into a train tunnel. The anvil from earlier smashes onto Sylvester's head and then another train runs down on him.
Sylvester is extremely upset, and tries to threaten to eat the bird. The bird calls Sylvester "Papa" and Sylvester kisses the bird, causing him to nearly eat it. At the end, Sylvester is now the father to a series of similar birds, who keep calling Sylvester "Papa," much to his dismay.
- The little bird is never explicitly given a name, but in one scene, Sylvester derisively calls it Cornbread.
