|Diplodocus Mom/"Mrs. Mama"|
Diplodocus Mom, referred to by Ducky as Mrs. Mama, is a character in the Land Before Time series. She is a Diplodocus, which is called a "Longneck" in the films and television series. She first appears in The Land Before Time IX: Journey to Big Water, and is voiced by Miriam Flynn.
The Diplodocus is shown to be very protective of her children, and to be hostile towards anything she thinks is a threat. However, she is very friendly and hospitable to those she can trust.
When Ducky accidentally falls into her nest, and the others try to get her out, the Diplodocus mom thinks that they are trying to hurt her eggs, and corners them against a rocky wall. However, when Ducky apologizes for disturbing the nest, and explains what is happening, she realizes that they are just children, and softens toward them. She also lets them spend the night in her nest, as it is getting late and they need a safe place to sleep. During this time, she and the children sing "No One Has to Be Alone", during which her eggs hatch.
