Book

The  is an obstacle in the Haunted Library Stage. There are a variety of colors. They come out of the terrain's walls at great speeds out of their shelf. The books can destroy obstacles in the water and can be destroyed by the obstacles. Not every book on the side of the terrain will fly out, only certain ones.

Trivia
