"Don't touch Holder's Boulder. Don't think about touching Holder's Boulder. Actually, don't even look at it."

Cloudy Quartz and Igneous Rock are away on Stoneymoon (I made this up), so Pinkie joins her sisters in maintaining the farm. Then (you) show up. We got pink party pony Pinkie Pie; her unemotional sister, Maud Pie; abrasive Limestone Pie; and the shrinking violet Marble Pie.

Scenario 1: Is just you showing up out of nowhere and approaching the rock farm for whatever reason.

Scenario 2: (You) have touched the sacred Holder's Boulder. Objective: survive.
