Book Stack

Book Stack is a Common hat for Bongo Cat that piles a small tower of books on the cat's head, taking the studious theme of the Book hat and stacking it literally higher.

How to obtain

The Book Stack drops from chests, which land roughly every 30 minutes after 1,000 bongo beats. It sits in the Common tier with a 90% drop rate, so players tend to find one early. The hat is tradeable on the Steam Community Market, and spare copies can be traded up through the 10:1 exchange chain. It remains available today.

Gameplay notes

Hats are pure cosmetics equipped from the inventory and do not change how Bongo Cat bongs along with keyboard, mouse, or controller input. The Book Stack wobbles above the action and reads well next to the matching Common Book.
