Monster Book of Monsters.
"A vicious guide to monstrous creatures."

The Monster Book of Monsters, by Edwardus Lima, is a particularly vicious textbook that is used in Care of Magical Creatures while Rubeus Hagrid (who thought the book's aggressive nature was funny) was the teacher.

The book will attack anyone who attempts to open it. The only way to subdue the book is to stroke its spine, upon which the book opens placidly.


"Hasn' anyone bin able ter open their books? Yeh've got to stroke 'em."
—Hagrid in his first lesson of magical creatures[src]

After incidents in which the books attacked each other, the manager of Flourish and Blotts vowed never to stock them again; he found the situation to be worse than when the entire stock of The Invisible Book of Invisibility disappeared.

When students brought this book to Hogwarts for Rubeus Hagrid's Care of Magical Creatures class, they had to force the books shut with belts and Spello-tape because they didn't know how to calm the books.

Rubeus Hagrid gave one to Harry Potter for his 13th birthday in 1993 as it was part of his requirements for his third year at Hogwarts School of Witchcraft and Wizardry.


The Book attacking Neville Longbottom

Hermione Granger considered this book along with many others as she was deciding on the supplies they would need to take on their mission to find Voldemort's Horcruxes. As she was sorting books, it broke free of its restraints and bit Ron Weasley on the ankle. It is unknown if she took it with them.

At some point in its history, Dervish and Banges apparently suffered a bad incident involving a copy of this book, as their instructions for their closing procedure included "Double check the lock on The Monster Book of Monsters! (you know what happened last time.)"[2]

Physical appearance

In the video game adaptations, the Monster Book appears as a jade-green book with gold engravings. In the films, the book is a grey-brown colour, has many rips inside, four beady hazel eyes and a mouth that bites anyone who tries to open it.
