As our heroes travel through a deep forest, Serena recalls a story about a particularly scary house. And just as they make their way out of a forest, they come across the mansion from her tale! On the doorstep of the scary house, a gentleman named Lon invites them in out of the rain.
Shortly after, our heroes witness a series of frightening and inexplicable events. But it soon becomes clear that these scares are the work of a Gastly, Haunter, and Gengar, all Lon’s good friends. The Pokémon don’t mean any harm—it’s their way of making guests feel welcome!
The real mystery begins when Clemont discovers a young boy’s journal and photo in the basement. As Clemont reads about the boy’s scary experiences in the house, Lon recognizes himself in the photo, which apparently was taken more than two hundred years ago…and then our heroes are in for the fright of their lives when their host calmly reveals that he isn’t exactly alive!
The next morning, our heroes wake up in the forest, wondering if their shared experience was all just a dream. Later, during another rainy night, a soaked Team Rocket arrives at the scary house. Lon invites them in out of the rain...
