Trivia

 * Bowser originally built a castle on World 1.
 * This is the planet most like Earth.
 * A leak in dimensions allowed Max, Zach, and Peggy to crossover into Mario`s timeline. The characters of Max`s timeline were aware of this. Mrs. Misses Teacher confirms this by saying that Wario`s hen, who was originally of Max`s timeline, went over in Mario`s timeline, came back, and was arrested due to her crazyness.
