Concept: “A klepto man duck's den”
Content: The den, the duckie, and a duck-based scroll
Writing: Short and concise but brimming with humorous character
Art/design: Includes an illustration and map; overall, high-quality and gritty graphic design
Usability: Intended for use within a larger dungeon but still pretty modular

Concept: “Hoodening is a folk custom […] where a person imitates a horse by hunching their back and holding out a horses head.”
Content: Items that grant strong benefits to users (at a potentially serious/hilarious cost) with some sample skeletons
Writing: A short rationale; primarily devoted to mechanics
Art/design: Graphic devices synergize well with illustrations and create a sense of sharpness and motion
Usability: Item mechanics are simple in themselves but could cause complications for PCs
