That is just to much cuteness. This makes me think she is a filly. Just to to much adorableness.
I can just see that her family are at the local strawberry farm. They go every year to help out friends harvest strawberries and also get some as well. Pinkie being to young at this time to be of much help is just left to play. While she does she sees one of the Strawberry Farmers prized Jumbo Berries. The farmers wife sees her drooling over the berry and laughs as she gives her one. Pinkie just plops down and rolls the berry up on her lap as she sinks her mouth into the berry. Just as she does. Her father and mother walk over to her. "They ask her what she got there". With out even lifting her head up to reply she muffles. "Swawbewwy!" As she beams her big eye and rosy cheeks. Pure joy fills them all as they watch her try her best to eat the berry.
