Escape From Shudder Mansion: Goosebumps Slappyworld (Book 5)

In an old-fashioned "trapped-in-a-haunted-house" story, twins Riley and Scarlett receive an interesting assignment from their teacher, Mrs. Stermon. Everyone in class needs to do a documentary video about an adventure, something exciting that they experienced. Mrs. Stermon gives them a suggestion, along with their friends Carter, Lee, Danitia, and Mia. She shows them a brochure about a scary old house on the edge of town, called Shudder Mansion.
