Ducky and Spike's Father is a minor character in The Land Before Time movie series. He is the father of Ducky and 12 other swimmers, the adopted father of Spike and the husband of Mama Swimmer. He first appeared in The Land Before Time eating grass and watching his wife lay next to their eggs which hatch. He doesn't appear again until the end of the film showing that he and Mama Swimmer and the other 12 little swimmers have made it safely to the Great Valley and when his daughter brings Spike and introduces him to the little ones as their new sibling he welcomes his new adopted son into the family. He makes a cameo in The Land Before Time II: The Great Valley Adventure in which he is seen laying next to Mama Swimmer in their nest at night. He was last seen in The Land Before Time 5 The Mysterious Island standing next to Mama Swimmer at the new place the Herd found to live at until the Great Valley gets green again and when the children arrive there on Elsie he goes with his wife to greet Ducky and Spike and in the end he waves goodbye to Elsie. He is isn't seen throughout the rest of the movie series after this. It is believed by fans that the reason he hasn't had a big role in the movies like his wife has is because that the original voice actress for Ducky in The Land Before Time Judith Barsi was murdered by her father before the movie was released.
