Pinkie Pie

Pinkie Pie is one of the major protagonists in the series, My Little Pony Friendship is Magic. She 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 babies, 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.

History
Pinkie Pie was raised on a rock farm with her two sisters and her parents. Her family's coats and manes are Earth-colored, muted browns and grays.

When Rainbow Dash's sonic rainboom clears the clouds and paints a rainbow across the sky, the shock wave frizzles Pinkie Pie's hair, giving it its distinctive curl. Subsequently, Pinkie Pie experiences magnificent joy and smiles. She then decides to dedicate her life to making people happy and throwing parties. When she invites her family to their first party ever, her mother calls her Pinkamena Diane Pie. An animator on the show, John Irving L. Prudenciano, revealed that Pinkie Pie's full name is Pinkamena Diane Pie a few months prior to the airing of The Cutie Mark Chronicles.

Story and Personality
Pinkie Pie is an outgoing, energetic pony who loves sweets and often speaks and acts in non sequiturs. She has a fondness of parties and a tendency to throw them on a whim. Pinkie Pie plays many instruments and frequently breaks out into song. She also tends to hop rather than walk, usually accompanied by a springing noise. She is often not taken seriously even by her closest friends, who call her out on her seemingly illogical behavior in Swarm of the Century, among other instances. She is almost always excited, and manages to keep her excitement after winning thirty-five consecutive games of tic-tac-toe against Rarity in Dragonshy while they wait for Fluttershy to catch up. Rarity adds with disinterest, "best of seventy-one?"Pinkie teaches the other ponies to laugh at their fears in Friendship is Magic, part 2 through an impromptu musical number, and helps Twilight accept things even if she doesn't understand them in Feeling Pinkie Keen. She plays a series of pranks on the residents of Ponyville with Rainbow Dash in Griffon the Brush Off, saying "[she] loves to have fun". She is very conscientious about this, though; when she pranks someone it's in such a way that no harm is done and the victim gets a laugh from it too. She'll never prank someone if she knows it might hurt them, such as Fluttershy because of her extreme sensitivity. When Gilda lashes out at Fluttershy and makes her cry, she decides to take measures against her "Pinkie Pie style" by throwing the griffon a party. Rainbow Dash set a number of different pranks for the guests at the party. Unfortunately, Gilda manages to become a victim of all the pranks. She assumed that Pinkie Pie had set all the pranks for her in particular, and was shocked to find that Rainbow Dash did it. When Rainbow Dash refused to leave with her, she left by herself in a rage. Pinkie shows her insecure and somewhat deranged side in Party of One. After her friends give her flimsy excuses for missing Gummy's "after-birthday" party, she breaks into a fit of paranoia which "deflates" her hair and ends up with her abandoning her friends for inanimate objects, pretending they are real. She even has an argument with them, complete with weird spasms. Rainbow Dash forcefully pulls her out of her unhinged party and drags her back to her friends. When she finds out her friends did not abandon her, she promptly returns to her usual cheerful self and her hair bursts into its normal shape.Pinkie also does not respond well to accusations of immaturity. In Baby Cakes, after asking the rest of the main six whether they are available to babysit (and having their offers rejected), Mr. and Mrs. Cake ask Pinkie Pie dejectedly if she could. Pinkie Pie is overjoyed; however, the Cakes warn Pinkie that babysitting requires "responsibility" that she may be overwhelmed by. In response, Pinkie insists "I can be responsible! Why, responsibility is my middle name! Pinkie Responsibility Pie!" Inevitably, the responsibility of taking care of Pound Cake and Pumpkin Cake indeed does turn out to be more than she expected. Twilight Sparkle, having expected as much, shows up at the door and asks if Pinkie would like any help since "some ponies just aren't cut out to handle the responsibility". Pinkie takes this as an insult, and promptly shuts the door, determined to prove Twilight wrong, yet insecure if she will manage to do so. Pinkie Pie's personality is magically altered by Discord in The Return of Harmony, part 1. Pinkie finds herself in a balloon garden filled with laughing balloons. At first, Pinkie enjoys it, calling it "the greatest balloon garden [she's] ever seen". However, one of the balloons latches on to her leg and lands her in a mud puddle, and the atmosphere changes into a menacing one. A bunch of other balloons surround her and laugh, and afterwards Discord appears and tells her that her friends were never laughing with her, they're laughing at her. The balloons, formerly sporting benign, smiley faces, distort themselves into the familiar faces of the main cast, even developing their voices and colors, and close in on Pinkie Pie, still laughing. Pinkie's eyes swirl in a "hypnosis" effect and her coat and mane become much grayer. She becomes moody and grumpy, and gets angered when anyone laughs or shows signs of pleasure, suspecting it's at her expense. Near the end of the next episode, Twilight restores her previous color and demeanor through a "memory spell". Afterwards, she is seen being carried away in a wheelbarrow, giggling and remarking "I turned gray! Can you believe it?"
