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. 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.
