Ducks, when talking, quack. When a single word is used, they quack once. When multiple words are used, they quack continuously. If a word not in the Toontown dictionary is used through the SpeedChat Plus option (assuming the player does not have the true friend option on), or other toons who do not have SpeedChat Plus, the word will be "censored" by "quack," "quacky," or "quackity." If an exclamatory phrase is used, the duck will quack loudly.
Ducks have four different head designs that can be used to create a toon through the Create-A-Toon process. They can be created in any color.
