On Ian's birthday, after he receives Slappy, Abigail is given as a present to Molly. Later, Molly plans to do a fashion show with Abigail. However, Slappy throws the doll into a goldfish tank. At the end of the story, Molly carries Abigail into the basement, where the family fight Slappy. However, Abigail comes alive and says the words to put Slappy back to sleep. Everyone is relieved - until Abigail orders them to clean up, then bring her lunch, dubbing them slaves!
Abigail was a tall, old-fashioned looking doll with red hair and a pretty pink face. She wore a long blue ball gown under a flowing red cape.
Like many living dolls in the series, she is resentful and annoyed at Slappy. She ends up destroying him, because 'she was tired of that dummy getting all the attention'. She is shown to be cruel when she then orders the Barkers to do chores and calls them slaves.
