The Apples quickly discover that the Pies have very different traditions around the holiday and are much less joyful than what they are used to. Applejack tries to liven the mood by introducing her family's traditions to the Pies, but in her haste, she causes Holder's Boulder—a giant rock the Pies hold dear—to fall into a quarry. Ashamed, Applejack and her family decide to leave. On the train ride back, Granny Smith informs Applejack that Holder's Boulder is a centerpiece of the farm and part of their traditions.
