This scenario is built for use with a Lasers & Feelings hack called Tricks & Treats, created by Octava Oculta (Reddit username u/shardsofcrystal). It's an ultra-lite system fit for all ages or experience levels, and is great as a nostalgic little novelty adventure. Just follow that link, make a copy of the folder and its contents, and use the materials within to play a fun session of spooky adventure.
Here's the pitch: play as middle schoolers on a field trip to a pumpkin patch on the morning of Halloween, encounter a big horrifying monster that the grown-ups are helpless to stop, use your noggin to save the day. This is especially good if used as a sequel to the last adventure because all the students have aged a year and you can build on previous events and relationships. That said, most of my own players created new characters for this year, so do what you feel like.
Not sure when part 3 will come out, but one of my players suggested we also do some spooky adventures during tax season, the other Halloween. If anyone runs either of these adventures, I'd love to hear about it and how it goes.
