True, heart-stopping terror takes many forms:
Foul beasts roaming the dark who consume their victims, flesh and soul.
The object of one's affections finding a diary they weren't meant to.
Being tardy.
But until now, Equestria has not known the meaning of fear. The past's petty concerns and phobias mean nothing this day, for today, Equestria shall experience unimaginable horror. Today, Pinkie Pie becomes a unicorn.
