The second officially licensed My Little Pony: Friendship Is Magic chapter book of a series of books by G. M. Berrow, and part of the overall My Little Pony (Generation 4) universe. Just like Twilight Sparkle and the Crystal Heart Spell, this also takes place some time after season three. This book is centered around Pinkie Pie and it expands more on her family by giving them official names and personalities. The main source of conflict for this book is the huge differences between Pinkie's exuberant personality and her family's stoic-ness.
This book provides examples of:
- All There in the Manual: Word of God confirms the individual identities of Marble Pie and Limestone Pie, which the book itself hints at but doesn't explicitly state. Later made clear in the Season 5 episode "Hearthbreakers".
- Continuity Nod:
- Early Installment Weirdness: Marble and Limestone Pie display none of the personality traits they'd have when they debuted in the show.
- The Ghost: Pinkie's third sister, Maud Pie, is only mentioned (and not by name). She's running the rock farm while her relatives are visiting Ponyville.
- Hammerspace: Pinkie pulled three sets of mini spring-loaded shoes just like hers seemingly out of nowhere. It was almost like magic, but it wasnt—it was just Pinkie.
- His Name Is...: After greeting Marble and Limestone, Pinkie Pie is about to ask where her older sister is, but Igneous responds that she stayed at the farm before Pinkie can drop her name. It's not until season 4 that we learn her name: Maud Pie.
- In-Series Nickname: Iggy for Igneous, and Limey for Limestone.
- Market-Based Title: The UK print of the book shortens the title to Pinkie Pie and the Rockin' Pony Party.
- "Metaphor" Is My Middle Name: Pinkie Serious Pie.
- Named by the Adaptation: The Pie family receives official names in this book, as does Davenport.
- Nice Job Breaking It, Hero:
- The Pies are having trouble selling rocks... because after the Crystal Empire was saved by the Mane Six, it started a jewel craze.
- Pinkie's parents ask Pinkie to be more serious, and it causes some major issues for a good portion of the book.
- No Name Given: Pinkie's third, older sister. The series proper reveals it's Maud.
- Shout-Out: Various ponyfications of artists: Nine Inch Tails, Switchhoof, Neigh-Z, Coldhay, the Whooves and John Mare.
- Sudden Name Change: Chapter 3 of the story mentions Sweetie Drops, while one of the bonus activity pages lists Bon Bon. These are two formerly separate official names of one pony, though she doesn't appear in the book herself.
