Bourbon, Berry, and Tater all live on Sweet Apple Acres, and Knick Knack lives in the edge of town closest to it. The four do typical family activities with each other like having dinner, hanging out, ect.; but when more kids come to town to visit, the party really starts! Cousin Fyreside from Appleloosa is a sports fanatic, and the twins' half-sister Scarlet Gala from Canterlot is an athletic Royal Guard. Therefore, the only natural thing to do is play Volleyball!
Kind of half-assed this one, but whatever. It turned out fine, if a bit sloppy.
