Goosebumps 2: Haunted Halloween

Teenager Sarah Quinn lives with her mother, Kathy, and her younger brother, Sonny, in the town of Wardenclyffe, New York and is writing an essay for her college application while Halloween is just around the corner. Sonny's friend, Sam Carter, is dropped off at their house to be looked after while his parents are away for the next three days.

Scavenging for items in an abandoned house formerly owned by R. L. Stine after school, they find an unpublished Goosebumps manuscript and unlock it, resulting in Slappy the Dummy appearing, who is currently inanimate. Leaving the house after obliviously reading the incantation that brings Slappy to life, they are intercepted by bully Tommy Madigan, who steals the manuscript from them. He and his friends attempt to chase the duo home, but are secretly stopped by the now-brought-to-life Slappy.

Back home, Slappy reveals his sentience to the duo, but requests that they keep him a secret from the other Quinns. The next day, Slappy tries to assert himself as a member of the family – first by assaulting Sarah's boyfriend, Tyler Mitchell, for recently cheating on her, then causing damaging to one of the classrooms of Sonny's school after sabotaging his science project, a working model of the abandoned Wardenclyffe Tower created by Nikola Tesla. Now aware of Slappy's true nature, the duo and Sarah settle on getting rid of him, only for him to escape when they attempt to do so.
