Ducky: Ducky has been called a "Swimmer," "Big Mouth," and "Duckfoot" on screen, so it is not known for sure what kind of dinosaur Ducky is. She looks most like a Saurolophus, but she is called a Parasaurolophus on the Land Before Time Website . She is the nicest of the group, and trusts others easily. She lives with her mother (though her father does not appear) and says in the sixth film that she is one of thirteen twins, although the original series tht she is one of four. She also has her adopted brother Spike.
