Step Right Up

Step Right Up is a milk-themed carnival horror adventure. Inspired by the modular train in 6:66 to Mephistar, this adventure features a host of two-part attractions from which the DM can build their ultimate extravaganza. In addition, it includes 10 new monsters, 5 original magic items, a couple of printable handouts, and tips for running horror in TTRPGs.

One Cool Thing. This adventure has a sweet and spoiled mechanic. Each attraction comes in two parts. At the beginning of the adventure, characters can fully experience an innocent (albeit creepy) carnival and all the sweet attractions it has to offer. However, in the second part of the adventure, each attraction is spoiled, twisting them into a horrifying reflection of what they once were!
