Ducky

Ducky (a.k.a. Devoted Ducky, as she is called in her bio on the official site, and referred to as by fans), (voiced by Aria Noelle Curzon) is one of the original five main characters in the Land Before Time films and television series, and one of only three characters to appear in every movie and episode of the TV series. Her species has been disputed by fans and critics to be one of such species as Saurolophus, Anatosaurus, and Parasaurolophus. Though her appearance bears more resemblance to Saurolophus, and she has been identified as one in The Land Before Time Sing-Along Songs video, she has been called a Parasaurolophus in most other official merchandise and media, and has even been called an Anatosaurus in a Land Before Time coloring book. She is one of many creatures called a "swimmer", and is also called a "big mouth", or a "duck-bill" by the characters in the films. Ducky is very out-going and positive, and is loving to her friends and family. She lives with her mother and father, multiple biological siblings, and an adopted Stegosaurus (which is referred to as a "Spiketail" in the series) named Spike, who is also a main character in the series. Together, they are friends with the other main characters, Littlefoot, Cera, Petrie, Chomper, and Ruby. In most cases, Ducky is listed after Littlefoot and Cera, and before Petrie and Spike, Chomper, and Ruby, but sometimes Spike is listed after Cera and before Ducky. The character of Ducky has been received well by critics, and has had considerable influence on culture, being featured in a large amount of The Land Before Time-related merchandise, and being a focus point in numerous fanfictions. She is most well known for frequently saying "Yep, yep, yep" and "Nope, nope, nope", both of which are frequently quoted in everyday culture and media.
