Pinkie Pie made her first debut in the aforementioned TV series in the episode Friendship is Magic - Part 1, where upon encountering Twilight Sparkle, she screamed and quickly dashed away. She appears again later at Twilight's house in which a surprise party that Pinkie Pie herself prepared for Twilight's arrival in Ponyville is held. Pinkie Pie once again appeared along with the other ponies witnessing the arrival of Nightmare Moon in the Summer Sun Celebration.
Pinkie Pie appeared once more at Twilight's library. She assisted Twilight in finding a book about the Elements of Harmony, which is believed can be used to defeat Nightmare Moon. Among all the others who were searching for the book, Pinkie Pie was the only one who found it, which she states was under letter "E" in the bookshelf. She joins the others on their quest to find the castle of the two sisters. During one part of their journey, the characters encountered scary - looking trees. When Pinkie Pie laughed at one, the tree reverted back to a normal one. Pinkie Pie then proceeds to sing on how Granny Pie told her to laugh at her fears when she was a filly. And so, the other characters laughed at the other trees until they turned back to normal.
During the part where Twilight and the other characters confronted Nightmare Moon at the castle, Twilight announced Pinkie Pie as the element of laughter for laughing at the face of danger, which gained Pinkie the aforementioned element. After they defeated Nightmare Moon, who turned back into Luna and was forgiven by Princess Celestia after apologizing, Pinkie Pie cried tears of joy.
