Bookends are regular, floating green books. However, they have eight large, spiky teeth in the inside of their pages. Furthermore, their visible pages are messily coated with a red substance with no visible handwriting.
Bookends can be found in a library on the second floor of Big Boo’s Haunt. They will begin to fly from bookshelves and attempt to collide into Mario, Luigi, or Wario (Yoshi is not applicable as he cannot enter the stage). There are several bookends in the room that can be nuisances if not dealt with correctly.
