Characters from the Goosebumps novel Bride of the Living Dummy
Mary-Ellen
Portrayed By: Julissa Aguirre (TV)
A doll owned by Jillian's little sisters, who take her everywhere they go but seem to be afraid of her and are always claiming that she does bad things. It turns out she's really alive and forces the girls to do things for her. And now she wants Slappy for a husband.
- Abhorrent Admirer: Slappy prefers Jillian as a bride, but she's insistent he pick her.
- Adaptation Dye-Job: In the book she's described having black hair, the TV adaptation turned her blonde.
- Blush Sticker: In the book she's described having blood-red Blush Stickers.
- Creepy Doll: She plays it straighter than Slappy in that she's an actual doll, not a dummy.
- Diabolus ex Nihilo: Unlike Slappy and the other dummies, there's no explanation as to how Mary-Ellen came to life. She was brought by Jillian's father and immediately forced Katie and Amanda into becoming her servants. It is possible that she was one of the evil toys made by the sorcerer that created Slappy, but it's not confirmed.
- Disproportionate Retribution: She reacts to Jillian disliking and resenting her by terrorizing her family and awakening Slappy so that they can enslave her for life together.
- Eviler than Thou: She's somehow even worse than Slappy in that she's been more successful in controlling young kids to do her bidding. Katie and Amanda are terrified of her, and in the TV show Katie explicitly tells Jillian that Mary-Ellen has threatened to hurt her family if she didn't do what she wants whereas Slappy simply wants to marry Jillian or Katie.
- Expy: Of Tiffany from Bride of Chucky. In the TV series she's given blonde hair and even sounds similar to her.
- Half the Man He Used to Be: She gets by cruelly sawn in two by Slappy throwing her onto the table buzzsaw of Jillian's dad.
- Killed Off for Real: Unlike the TV adaptation, in the book Mary-Ellen seems to have died off for good when she's cut by the buzzsaw, and only Slappy possesses Jillian with his spirit.
- Taking You with Me: In the book, after being sawn in half, Mary-Ellen uses her remaining forces to grab Slappy by the legs with the upper side of her body and gets him cut in half onto the buzzsaw.
- Unholy Matrimony: What she wants with Slappy, but he's not interested.
- Woman Scorned: When she finds out Slappy wants Jillian for his bride, she flips out and tries to kill him. What makes her especially mad, in the book at least, is that she was the one who revived him in the first place.
- Would Hurt a Child: In the book, she convinced Katie and Amanda to be her slaves under the threat of hurting them. She also steps over a terrified child on the ground after revealing to be alive and confronting Slappy for wanting Jillian over her.
- What Happened to the Mouse?: Unlike the book, we actually see her spirit escape her destroyed body in the show, but we never see where it went.
