Errors
There are quite a few errors about the timeline of this book, though it may be due to a penguin making up the story.
 * The Everyday Phoning Facility is open even though Shadow Guy and Gamma Gal were discovered before then.
 * Also, Amy meets the Sensei, even though no one knew of his existence at the time the stage play was released.
 * The Dojo Courtyard is also open though it wasn't supposed to be open at the time.
 * There is an Aqua-colored penguin in the Pizza Parlor even though the color didn't exist yet at the time the stage play was released.
 * Issue 246 is written by Aunt Arctic but it is not real, the real issue was on a different date with different things in it. The stage play came out way before the date on the fake issue as well.
 * The Orange and White Puffles are in this book though they hadn't been discovered at the time the stage play came out.
 * Gary and Sam are in the old lab, even though the Everyday Phoning Facility is in the book.
 * When Shadow Guy takes the shadows of the citizens of Club Penguin, a part of a girl penguin is white, not colored.
