The second chapter ends with Jillian grimly stating that another thing she and her sisters didn't know was that going to Jimmy O'James' show would've ruined their lives.
Slappy making Jimmy's nose bleed with a hard slap to the face. In the previous books Slappy has shown to be violent with his victims, but this is the first time he hurts someone strongly enough to make them bleed. It makes the final confrontation in which Slappy threatens to hurt Eddie much more terrifying.
The whole setpiece at Jimmy's abandoned house. Jillian and Harrison find it in utter decay and extremely dark, inside they get freaked out by what they first assume to be Jimmy's decapitated head on a table before realizing it's a dummy head with his likeness, then they discover that the whole room is filled with dummy body parts. After reading his diary, they hear slow, dragged footsteps approaching and Jillian freezes in fear thinking it's a living dummy coming after them, before it's revealed it's just Jimmy's elderly neighbor who wanted to check on who entered the house.
Jimmy's diary states that the sorcerer who made Slappy created cursed Living Toys that would hurt and steal from the people he sold them to. Enjoy the Paranoia Fuel about those bloody things being still out there.
The following part in which Jillian has to babysit her sisters while her parents leave for the night.
She returns to her room only to find "Where Is My Bride?" written with lipstick on her mirror, Slappy sitting nearby. By this point Jillian is convinced that Jimmy's behavior and his diary confirm that Slappy is truly alive and evil, and she's left home alone with him just as she needs her parents the most.
She tries to keep her cool and watch over Katie and Amanda as they dine, but then when she goes to the bathroom the entire house shakes violently and hears her sisters shrieking their heads off. Jillian rushes to the dining doom and finds it in complete chaos with food everywhere, while the crying twins scream that Slappy did it, who is inexplicably sitting at the table.
Jillian goes to answer a phonecall from her mom wanting to check on the situation, and Jillian can't take it anymore and cries about what just happened, but her mom only gets very disappointed in her and claims that they'll try to get home soon, more annoyed than concerned about her clearly panicking daughter. Then Jillian notices Slappy is gone, the twins are frozen in fear. Then she hears something stomping its way upstairs. She rushes back to her room... and finds Slappy once more, with "Where Is My Bride?" written on the wall now. The Nothing Is Scarier approach is chilling.
The entirety of the final confrontation during Eddie's birthday party. First Jillian is horrified when she finds Slappy instead of Maxie (a non-living dummy Harrison had gotten for her), then Slappy terrorizes everyone by vomiting green ooze like Mr. Wood did in the first book and reveals that Jillian is his bride, giving her a violent "love tap" headbutt and then Mary-Ellen revealing to be alive and being furious about the rejection.
The whole aspect that a Perverse Puppet was already present in Jillian's life is just terrible, one can assume that even if they didn't go to Jimmy's show and got Slappy involved, eventually Mary-Ellen would've done something awful to Jillian once she couldn't stand her anymore, it's a ticking time bomb. Had Jillian made it through the whole affair without the Mandatory Twist Ending, it's very likely that she and her sisters would've banned any kind of dolls and puppets from their lives out of sheer Paranoia Fuel of having a seemingly innocuous toy being actually alive, dangerous and actively scheming against them.
Slappy and Mary-Ellen brutally fighting each other in a basement filled with terrorized children. It ends with Slappy activating the table buzzsaw of Jillian's dad and throwing Mary-Ellen into it. She's still alive enough to grab him and doom him to the same fate, but before that Slappy lets out a triumphant Evil Laugh that is described being louder than the buzzsaw.
The TV episode
Mary-Ellen, Katie's doll, may be more disturbing to look than Slappy himself, due to being an actual plastic doll, and her facial expression doesn't change all that much apart from her angry face, bringing us a good case of Uncanny Valley. She's also very cruel just like Slappy, seeing as she forces Katie to do what she wants under the threat that she will harm or kill her family if she refused. It gets worse when she falls in love with Slappy.
Like the other two Living Dummy episodes, this one also has a disturbing ending. When a fight breaks out after Slappy's rejection of Mary-Ellen, Jillian is quick to turn on the saw-blade in the basement. Slappy tries to throw Mary-Ellen on the blade, only for the doll to hang onto him, and they both get torn to shreds (off screen, save for pieces of wood and plastic falling on the floor). What's left of their bodies are seen on the floor, and while Slappy's expression seems to be the same, Mary-Ellen's angry face is locked in place, and their evil spirits fly off when the carnage is over. The next morning, everyone gets a nasty surprise when it's revealed that Slappy's spirit has possessed Harrison, and laughs maniacally in his first stages of Puppet Permutation with large bulging eyes.
Slappy: Heh, heh, heh! Sorry, folks! Harrison doesn't live here anymore! (laughs maniacally)
