Record Book
A bamboo tsunami uses its drops to carry out its specialty, which is turning itself into record books.
The bamboo tsunami hits the ground and drops of bamboo turn into sheets of paper. The sheets of paper combine to become record books that record what happened here, on this day.

A record book is a book (ぼ), when it comes down to it.
Bamboo can also become bo staffs too, if they don't turn into record books.
