Chomper (a.k.a. "Eager Chomper", as he is called on the official website, and by fans), originally voiced by Rob Paulsen, later Cannon Young, and now Max Burkholder, is a character in the The Land Before Time films and TV series. He is a Tyrannosaurus, which is one of many species of carnivorous dinosaurs called "sharpteeth" in the Land Before Time series. He first appeared in The Land Before Time II: The Great Valley Adventure, when he was hatched by Littlefoot, Cera, Ducky, Petrie and Spike. Being raised by them for the first day of his life has led him to be friendly with herbivorous dinosaurs, although they do not always trust him. He is bilingual, being able to speak both the herbivore language of the plant-eating dinosaurs (heard as English to the viewer), and the "Sharptooth" language of the carnivorous dinosaurs, which seems to consist of grunts, roars, and clicks, which makes him quite useful in solving disputes between the herbivores and carnivores.
Chomper was so well-received by the fans and critics of the series that he was brought back as a supporting character in The Land Before Time V: The Mysterious Island, and re-introduced as a main character in the television series.
In the LBT-Humanization Series, when Chomper's or Michael's friends are out or not available, the both go out to town, eat, or go see a movie.
