Pinkie Pie

Pinkamena Diane Pie, more commonly known as Pinkie Pie, is one of the main characters of My Little Pony Friendship is Magic franchise.

Pinkie is a pink Earth pony who is often seen hanging out at Sugarcube Corner, whether assisting Mr. and Mrs. Cake at work or babysitting their infants, or holding parties for the various ponies of Ponyville. She writes and performs many songs, and has a toothless pet baby alligator named Gummy. She represents the element of laughter.

In the AWA fics, Pinkie debuted on Chapter 9 of All Worlds Alliance Missions - Rainbow Rocks.

Appearance
Pinkie is an Earth-pony with a pale, light-gray raspberry coat, with light cerulean eyes and a curly brilliant raspberry mane.

Personality
Pinkie is hyperactive, excitable, quirky, and outgoing, often speaking and acting in non sequiturs. She warmly welcomes new faces such as Twilight Sparkle and Cranky Doodle Donkey. True to the element of laughter she represents, she loves to make ponies smile and laugh.

Pinkie tends to have a lighthearted manner in serious situations, such as stopping to drink chocolate milk raining from a cotton candy cloud when the main characters confront Discord in The Return of Harmony Part 2. As a result, she is often not taken seriously even by her closest friends, who occasionally call her out on her seemingly illogical behavior.

In The Return of Harmony Part 1, Discord hypnotizes Pinkie with his chaotic magic. In this state, Pinkie is an irritable grump who hates laughter and happiness and has a general dislike of many things. When she's returned to normal in the following episode, she laughs and says, "I-I turned gray! Can you believe it?!".

Pinkie Pie is first introduced as a talented and avid party-thrower. She throws a party for Twilight Sparkle in Friendship is Magic and a welcome party for Gildain Griffon the Brush Off, and a birthday party for Gummy in Party of One (and even an "after-birthday party" the following day). Pinkie is even shown to throw parties on completely random occasions, such as a "finish ringing the school bell" party in Castle Mane-ia.

In The Cutie Mark Chronicles, Pinkie says she got her cutie mark when she was inspired to throw her first party for her dour family. In Party Pooped, Pinkie is revealed to have a secret party planning cave in the Sugarcube Corner basement.

Abilities
Pinkie frequently performs songs and plays a variety of musical instruments in the series. She plays a one-pony band in Swarm of the Century and Magic Duel, as well as the pipe organ in Castle Mane-ia despite having no prior knowledge of having played said instrument. During an afternoon in Party Pooped, she plays drums—mostly matching those of her human counterpart earlier in RainbowRocks—in a traveling band with "Liam T. Walrus", "Paul McCartneigh", and "George Horrsen".

However, in The Crystal Empire - Part 1 and Yakity-Sax, Pinkie proves to be inept at playing both a crystal flugelhorn and the Yakyakistan instrument, the yovidaphone. In Honest Apple, she expresses an interest in learning to play the guitar.

Pinkie works at Sugarcube Corner, a confectionery run by Mr. and Mrs. Cake. She teaches Apple Bloom how to make cupcakes in Call of the Cutie and sometimes comes up with her own outlandish recipes, such as cupcakes topped with hot sauce in Friendship is Magic, part 1 and a "chimicherrychanga" in The Last Roundup.

In Feeling Pinkie Keen, Pinkie reveals her ability to predict events in the near future by interpreting various twitches and involuntary motions, which she calls her "Pinkie Sense." The citizens of Ponyville pay heed to Pinkie's predictions, according to Applejack. Twilight is skeptical of the Pinkie Sense at first, since she fails to find a scientific explanation for it, but she eventually accepts it.

In The Mysterious Mare Do Well, Pinkie saves a team of construction workers from a collapsing building as part of the "Mare Do Well" plan. After Pinkie mentions her Pinkie Sense, her tail twitches, and she pushes Rainbow Dash out of the way of a falling pot. In It's About Time, Pinkie says she can only predict immediate events and not the actual future. Her tail twitches and a flowerpot falls on Twilight's head. In Princess Twilight Sparkle - Part 1, her tail twitches before a plunderseed vine knocks into Rarity.

In The Gift of the Maud Pie, Maud Pie claims to have a similar ability called "Maud Sense", and in Pinkie Pride, Cheese Sandwich displays a "Cheesy Sense".
