<P> Littlefoot has been referred to by several species names throughout the series . In the first film he is called a Brontosaurus on the home video packaging and by numerous media outlets . He was also called a Brachiosaurus on the later - released VHS clamshell case and Rotten Tomatoes UK . He is now listed as an Apatosaurus the official website and in modern incarnations of the series . </P> <P> He was originally named "Thunderfoot" by the creators of the first film, until it was discovered that a Triceratops character from a children's book had the same name . The original name was kept very late into production, up until just before the movie's release . Littlefoot has been compared to characters such as Disney's Bambi, and Dorothy from The Wizard of Oz, on how he goes on a strange journey and meets many new friends along the way . </P> <P> Cera, voiced by Candace Hutson (I - IV), and Anndi McAfee (V - XIV) is a female orange Triceratops, or "Threehorn". Like Littlefoot, she hatches in the first film, and is later separated from her parents and sisters during an earthquake . She accompanies Littlefoot to the Great Valley where she is eventually reunited with her father . She is stubborn, boastful, sometimes reckless, and occasionally belligerent, but is often made look foolish when she is proven wrong . The initial film, and a few sequels, attributed an ego to her species, especially to herself and her father, but this is diminished in later appearances . In the movie Invasion of the Tinysauruses, her dad begins a new relationship with a Threehorn named Tria, who Cera dislikes at first, but eventually comes to accept . By the following film, Tria and Cera's father have become mates, and have a child named Tricia, Cera's half - sister . </P> <P> The character was originally conceived as a male Triceratops named "Bambo", but was changed to a female named "Cera" at the suggestion of producer George Lucas midway through animation of the first movie . Hal Hinson of The Washington Post called Cera "a fiercely cute and rambunctious little dynamo" in his review of the 1988 original, with critic Mark R. Leeper likewise calling her "cute and pugnacious ." She was the main character of the 2001 children's book The Land Before Time: Cera's Big Day Out by Molly Goode, Judy Freudeberg, and Tony Geiss, as well as the 2007 book Cera's Shiny Stone based on the TV series episode "The Canyon of Shiny Stones". </P>
