Almost every spot inserves a purpose. Unused corners of the valley host secrets, like the statue in the Lost Woods, and almost every place in Pelican Town is used regularly by the villagers.
The only exception to the tightly planned out spaces in the game is in Pierre’s General Store, where one giant room seemingly has no purpose.
That room is the chapel to Yoba, an area that feels a little out of place in the rustic Pelican Town with its gold decorations and religious implications.
However, as of update 1.6, the chapel has been given a purpose. That new purpose only relates to one item in the game, which already has a small drop rate, so most players may have never seen it.
However, since the item in question is one of the scariest items in the usually wholesome game, the new chapel effect goes a long way to letting spooked players sleep a little more soundly at night.
