Daddy Topps (aka Cera's Dad in later films, Topsy, as he is called by Tria and Mr. Threehorn as he is called by the other grownups in the Great Valley) is a character in the Land Before Time films and television series. Voiced by Burke Byrnes in the first film, and John Ingle from the second to present, he is a Triceratops, and the father of main character Cera. He was credited as "Daddy Topps" in the first film and "Cera's Dad" in the first ten sequels. Most of his peers called him "Threehorn" or "Old Threehorn", while Grandpa and Grandma Longneck call him "my friend" "Mr. Threehorn" or "Old Mr. Threehorn". In the eleventh installment of the film series, The Land Before Time XI: Invasion of the Tinysauruses, the new character Tria, an old sweetheart of his, called him "Topsy". Since then, many assume that Topsy is his real name, although there has been argument over whether it is really his name or merely a pet name given to him by Tria. Cera was visibly angered when Ducky called her father Topsy, but it is possible that Cera didn't know her dad's name, and disliked it because she had learned it from Tria, whom she was envious of for taking most of her father's attention from her.
In The Humanization Series, Even After Michael Saved The Planet, Topsy Doesn't Believe Humans Are Useful, Until After Michael Saved His Wife From Raptor Dyne.
