Shared Universe

While reading through all the theories on here about the "entity" actually being a forced split-personality mechanism, I can't stop thinking about the wider world-building Curry Barker gave us.

The fact that the One Wish Willow stick isn't some ancient, one-of-a-kind relic found in a dusty tomb—but a mass-manufactured product complete with branded packaging, a crystal shop origin, and an actual customer service hotline—means the door is wide open for an absolute banger of a shared universe.

What path would you like to see a shared universe go, surely a prequel about the wish company is inevitable.
