Bookend

A Bookend is a large living book with sharp teeth that comes out of book shelves and flies toward Mario. The green books disappear if they hit anything, including Mario. They are found solely in Big Boo's Haunt in the games Super Mario 64 and the DS remake Super Mario 64 DS.

Bookends often only come out if Mario gets too close to them, and they attack faster as the plumber is closer to them. If Mario Jumps below the possesed books, they disappear and release a Blue Coin. If Mario is hit by a Bookend, he loses two life points.
