There are a total of four History Books that are used to solve a puzzle in the Rubber Prison, in which the books must be arranged on a shelf in the library in the correct order. Placing them in the correct order reveals a Wooden Crank that can be used in the Warden's Office to open the path to the Giant's Liar bridge.
The order can be inferred from the items' descriptions, placing them in the order that would logically complete the story they tell. The correct sequence of the books is blue, green, yellow, red.
How to Acquire
- The red book is obtained in the prison cell room on the first level, in the upper-middle cell next to a burglar.
- The green book is obtained in the Warden's Office on the second level, atop a bookshelf after freezing a geyser.
- The blue book is obtained in the Cafeteria on the first level, to the left of a Wasp Bomber.
- The yellow book is in the library on the third level, on top of a shelf.
