If you need instructions on how to get through the hotels, check out The Enclosed Instruction Book. Mario
The Enclosed Instruction Book, at one point being as large as Earth.
The Enclosed Instruction Book is a Mario's ultimate 4d weapon. It was forged long ago by the Ancient Geeks and is rumored to be sentient, but little is known about it since it interferes with recording mechanisms on most spacecraft. It takes no side in battle, but instead protects warriors of both good and evil; studies have shown that, without it, the Mushroom Kingdom would be constantly terrorized by threats such as intense solar wind and devastating meteorites. Not to be mistaken for the all spark.
Because of its mighty electric power, few have been able to survive touching the Enclosed Instruction Book. It is said in legends, however, that Mario once did and somehow lived, albeit changed forever; jolts of Instruction-energy morphed his catchphrase from "It's-a me, Mario!" to "If you need instructions on how to get through the hotels, check out the Enclosed Instruction Book."
The Instruction Book is featured in the final level of Super Weegee Galaxy, Bowser's Enclosed Instruction Book Reactor. The game reveals that Bowser was attempting to harness the Enclosed Instruction Book's power and use it with the evil intentions of forcing the Mushroom World's people to buy him doughnuts or DIE. In an epic battle atop the "Enclosed Instruction Book Reactor" with which the Koopa King was attempting to harness the Instruction powers, though, Weegee was able to defeat Bowser, who was sent plummeting, ironically, into the depths of the Instruction Book itself, which consumed him. He was later regurgitated, though, because he forgot his deodorant.
The Enclosed Instruction Book after it was made smaller
The book became so big that the Ancient Geeks asked Mario to push new pages into the 4th Dimension, making it being finally able to be held within a person's hand. Currently, the book's 4th length is as deep as the distance between Germany and New York, taking the shortest route through the Earth of course. It is theorized that this book also has parts within higher dimensions, some as long as Neptune, but we can't verify those claims.
Being written in the time of the Ancient Geeks, a lot of older, ancient texts are illegible, and sometimes get replaced with new English versions when the ancient papyrus breaks down.
It is also an enemy of the King's infamous Dinner Blaster.
