In Three of a Kind, Brenda the Duck is feeling a lot more cheerful than usual, only her friend Derick has been to visit her. She is sitting on a nest beside her pond, and she tells the animals that there is going to be a little celebration with 3, different special guests.

The animals ask Brenda the Duck what the guests will be called, and every time the animals and rats give an answer, Brenda keeps telling them the answer is wrong. By the end of the day, Brenda the Duck gets up, her 3 white eggs crack, and 3 yellow ducklings come hatching out.

Finally, the animals have a party by the pond, while Brenda and her 3 guests take a cruise around the pond. All in all, it really and truly is a day to remember.
