Unlocking the five Grand Tomes in Yooka-Laylee means opening a whole new world of activities and collectibles. However, each tomes require different number of Paiges needed to unravel another exciting level in the game.
First Grand Tome in Yooka-Laylee is called Tribalstack Trophics. Opening the tome does not require any Paiges. All they have to do is to head to Hivory Tower and find the statue near its door. They will find a slope, which players will then have to roll over using the duo's combo roll.
Unlocking Glitterglaze Glacier requires three Paiges, if they have the items, they should head to the room with a Captial B statue. Inside, they will find a ramp that they will need to open the door. Players can use their Buddy Slam skill to do that, according to Twinfinite.
In the next room, they need to answer Quack-Fire quiz before jumping on the ledge found at the right side of the room. Trowzer the Snake will teach them to glide in order to reach Glitterglaze Glacier. They have to glide over the gap to do that.
Next, they have to unlock the Moodymaze Marsh. In order to do that, they should head to the Archive room and talk to Trowzer so he can teach them another move. After that, they have to jump inside the giant aquarium and swim towards the bottom of the second tank. They need to push the button by slamming themselves while inside an air bubble.
It will open up a secret library and they need to enter the Waterworks section. Again, they need to jump in it. They have to wear an air bubble to walk across the floor. Players need to check for a jack-o-lantern logo on the pipes and they should enter through it. They need to swim until they reach the top.
In order to access Capital Cashino, they will be needing 10 Paiges. Once settled, they will return to Waterworks and with a new ability called Grapple. They will be using it to jump to the central turbine and the catwalk at the left side of Moodymaze Marsh.
After that, they need to grapple up and suddenly drop themselves to enter the door to reach the left-lined pipes. They will come out at the Hivory Tower and immediately go to Trowzer, as they have to buy another move from him. They need to be invisible before pushing the button and entering the next Grand Tome.
Lastly, the Galleon Galaxy's path is accessible at the Cashino. In order to reach that, they need to head back to the main area of the Hivory Tower. They must avoid the security cameras before they can talk to Trowzer again.
They need to unlock their flight ability to cross the narrow path with green sludge. After reaching the end of the path, they will find a door on the left. They can enter the last Grand Tome through that door. After completing all of them, they will earn the Open Books trophy in Yooka-Laylee.
