The cover shows Slappy the Dummy sitting on a girl's bed, with two stuffed animals.
In this particular story, a girl named Amy Kramer performs with her dummy, Dennis, every Thursday night at her family's little "talent show". Unfortunately, Dennis has become almost unusable with age, and his head keeps falling off. Jed uses it to pretend to be Dennis on one occasion. Soon after, Amy's father buys her a new one at a pawnshop that just happens to be Slappy. They find a moldy sandwich cramed inside his head, presumably the work of his previous owners, Kris and Lindy Powell.
After Amy reads the little card with the magic spell inside Slappy's pocket (karru marri odonna loma molonu karrano), Slappy starts to cause a lot of accidents, including slapping Amy's father on the cheek, ruining a birthday party, and trashing her sister Sara's bedroom. Amy's sister, as well as her younger brother Jed, repeatedly accuse Amy of doing all these things, and Amy's parents believe them. Amy gets punished for all of the accidents. But one night, she hears Slappy breaking out of the closet inside of her bedroom that she keeps him in. She sees the dummy actually walk out of her bedroom to Sara's bedroom and ruin her watercolor painting even further and seeing Slappy paint Amy's name repeatedly on the wall.
Sara soon confesses that she saw Slappy wrecking her bedroom. The two girls decide to prove it, by having their parents see him moving, with Jed disguised as Dennis again in order to shock Slappy long enough for the girls to grab him.
When the lights come on, "Dennis" does startle Slappy and knocks his head into Sara's iron bedpost, breaking it in two. However, when Jed turns out to have been asleep the whole time, it is implied that Dennis himself has come to life to stop Slappy (and he even comments that he's "part of the family again" in the television series).
