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 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.
