The... ShopName?

The... ShopName? is an event that can be reached with the Wildcard: Shops Neutral Effect from the Wildcard: Shops (Pyramid Trap Card) item. It cannot simply be a random event.

Upon continuing in the event, you go to the It's A Trap! subevent, which functions exactly like the So It Begins... subevent of the Deadly Pyramid (aside from having a mining opportunity), serving as a preface to the Inner Pyramid Random Subevents.
