Pinkie Pie

Pinkie Pie or Pinkie is a medium-pink Earth pony with lighter pink hair. Only her name, eye color, cutie mark, and fact that she likes to throw parties are similar to her G4 counterpart.

Depiction in the series
Pinkie Pie is smart, helpful, calm, easygoing, likeable, and good at planning. She loves the color pink and is, well, pink! Pinkie tends to use the words "absolutely", "positively", and "definitely" in her speech. When she was younger (shown in Starsong and the Magic Dance Shoes) she had a chipmunky voice and a voice crack. Pinkie describes herself as the best party thrower in Ponyville, which is most likely an exaggeration.
