Released in 2012 as an open edition, this set features eleven pins representing various busts, tombs, and crypts from Disney's Haunted Mansion attraction.

Here are the rules of engagement: 1. Always use a clear subject-verb-object structure to describe the front of the pin. 2. Mention specific details like 'marbleized fill' or 'randomly selected pins' without using lists. 3. Explain the mechanism for decoding the mystery in a narrative flow. 4. Conclude with an invitation for the user to try the puzzle.
