I think there is more to Pinkie Pie then you give her credit for. Honestly, a character like her is extremely fantastic since she is always excited about everything, always happy and always eager to help. I will agree that PP is not the most important, but she isnt Chris Tucker. She has internal strifes and desires with the same sensitivity about her talent and character depth as any of the other ponies. I envy her, because Pinkie tries her best to make everyone happy, which is not only a harder goal then any of the other goals of the mane six, but nearly unobtainable.
