Grand Tomes are books located throughout Hivory Towers and are used as a way to travel from Hivory Towers into the game's respective worlds. Once Yooka and Laylee stand on a Pagie Pedestal, they can speak to the Grand Tomes. A Pagie will then ask if they want to expand the world for a specific price of at least two Pagies more than the original unlock cost, the player can wait to expand the world for any period of time desired. Each book's design cover is related to the theme of that world.
Concept Art Edit
There is a sixth world book that is never accessed in normal gameplay. It is the green book that Capital B and Dr. Quack get sucked into. It has Tribalstack Tropic's pattern on it.
