Bride of the Living Dummy

Bride of the Living Dummy is the second book in the Goosebumps Series 2000 book series. It was released in 1998.

Plot
Jillian's two bratty younger sisters, Katie and Amanda, convince Jillian to take them to a ventriloquist show where Jimmy 'O James and Slappy are doing a comedy act. Slappy is actually pure evil and is controlling 'O James. When Katie and Amanda bring their doll, Mary-Ellen, whom they take everywhere and whom Jillian despises, on stage, Slappy insults them. After the show Katie and Amanda look for Jimmy to tell him about how hurtful the things he made Slappy say, but instead find him in a trash can. They decide to take the discarded dummy home, and Jillian performs at her house using Slappy. Slappy comes to life and wreaks havoc, trashing the party and attacking children. He shouts: "This is My party now and I want MY BRIDE!

Slappy steals their Mother's wedding ring to give to his Bride-to-be, and begins chasing the children around the house, trying to get his Bride. It is later revealed that Mary-Ellen is just as evil as Slappy, and has a human slave, Katie, just like Slappy. Mary-Ellen also reveals that she was the one who brought slappy to life because she wants to marry him, and Slappy was never alive until the party. Slappy rejects her advances because he actually wants Jillian as his bride. This enrages Mary-Ellen, and the two rumble until they fall onto a buzzsaw, and Jilllian turns it on, cutting the two dolls into pieces.

Fact: In the end of the episode, it's Harrison that gets the evil spirit. Not Jillian.
