Quacker Jeff Duck is a recurring character in the Tom and Jerry series. He is a yellow duck. Quacker is normally getting chased by Tom Cat in the Tom and Jerry series and Jerry Mouse is trying to save Quacker from getting eaten by Tom. Another recurring character in the series was Little Quacker the duckling, who was later adapted into the Hanna-Barbera character Yakky Doodle. He appears in Little Quacker, Just Ducky, Downhearted Duckling, Southbound Duckling, That's My Mommy, Happy Go Ducky and The Vanishing Duck. Quacker talks a lot compared to Tom and Jerry. In many shorts, he is the only one who speaks. He's very trusting, even trusting Tom in many situations in which Tom wishes to eat him. He's a friend of Jerry, but unlike Jerry harbors no hard feelings towards Tom. Quacker is often mistaken as appearing in The Duck Doctor, but the Duck appearing in that short is a wild duck.
