Book Summary

Perry page number

Perry in halftone

Speed Demons is a near word-for-word adaptation of the episodes "The Fast and the Phineas" and "Rollercoaster", presented as Part One and Part Two. The book makes the transition from Part One to Part Two with the simple phrase, "It was another beautiful summer day". Differences between the book and the episodes as broadcast are noted below. In general, most of the differences are that of timing, where an event is described as happening at a slightly different time (usually before) than when it happened in the episode, though some lines are missing from the episode.

Each page typically has a picture from the episode that helps the reader visualize what is being described. The picture is a halftone screenshot from the episode (taken from the wide format originals), cropped into custom shapes such as rectangles with cut-out corners or elipses. Each chapter includes a picture of Phineas and Ferb at the beginning of the chapter, and Perry's image appears next to each page number.


Background Information

  • The pictures are from the wide format originals. The series as broadcast on Disney Channel and Disney XD, as well as the DVDs, are in standard 4:3 format.
  • Gretchen is specifically named as the Fireside Girl who asks about the engine. In the episodes, this information had to be pieced together from the credits of two episodes.
  • The songs are described in general terms, rather than specifics. (For example, no lyrics are transcribed.)
  • Part One provides general info about Ferb being from England.
  • Part Two provides more info on Ferb, and provides a transition between the two halves that does not require that "Rollercoaster" be covered first, even though it is the pilot episode.

Production Information

Title Description

Lazy summer days? Not for Phineas and Ferb. One day the duo fixes up their Linda|mom's car and takes it to the races. The next they build the world's craziest roller coaster! The neighborhood's not likely to be the same after this. But will Dr. Doofenshmirtz plan to reverse the spin of the earth with a magnet trained at the eastern seaboard succeed and ruin things for everyone?

Back Cover Summary


It's summer vacation for Phineas and Ferb, and they have a lot to do! First, they fix up their mom's car and enter the Swamp Oil 500 at the speedway. Then, they build a wild roller coaster with more surprises than you can imagine—including snakes! With all this racing around, who has time to be bored?

Doofenshmirtz quote: "Ah, Perry the Platypus. You're just in time to witness my Deflatanator Ray!"
