When Scooby was younger, Mama-Doo had light brown fur and brown hair. She wore a pearl necklace and a scarf on her head. She also applied lipstick. During Scooby's adulthood, she had gray hair and her fur became a little wrinkly and she wore a pink dress.
She and her husband share several personality traits with Scooby, being scared easily, don't understand Shaggy's jokes, and love of eating. She loves her children very deeply, especially her eldest son.
She gave birth to Scooby Doo in the Dooville Veterinary Hospital. When her husband came into the room, she asked if their new baby looked beautiful. Then the newborn said Scooby Doo, so Dada decided to name him that.
One night, when she and her husband were on a date, they saw a puppy being threatened by Buster McMuttMauler. They chased him to his truck where he got in trouble with his boss for stealing dog collars. They all laughed when he was taken to jail.

She attended the family reunion at the Knittingham Puppy farm, where she and her husband were kidnapped by the ghost of Buster McMuttMauler.

She saw Scooby being framed for the ghost attack at the White House on TV. Fearing his arrest, she and Dada-Doo went to help clear his name. While the gang was trying to stop the ghosts from escaping she and Dada (riding in a helicopter) came to help. She tossed Scooby's galoshes to him, but landed on the ghosts instead, which caused them to crash. They celebrated at the President's banquet in Scooby's honor afterwards.
The 13 Ghosts of Scooby-Doo
When Scooby had enough scares, he quit the gang and moved back with his parents. When Shaggy called trying to get him to come back, she said that he still didn't want to come back and that his ghost-chasing days were over. However, Scooby did return after witnessing the terrible future if he didn't.
When the gang decided to take a break and visit Scooby's parents, she and many of Dooville's citizens gathered at the train station to welcome him home. However, before Scooby returned, Professor Phantazmo's circus came to town and upon hearing that everything was free, they all took off, completely forgetting about Scooby's homecoming.
