Bombers' Notebook

The Bomber's Notebook serves as a crucial menu item for completionists. The notebook details the times, days and locations of available sidequests that Link can complete by character. It can be found in the menu, where it will appear as a small icon in the top-left corner. The notebook serves as a guide for solving the problems of the residents of Termina, which ultimately leads to finding many secrets, masks, getting upgrades and unlocking cutscenes at the end of the game.

Obtaining the Notebook

The Bombers are an exclusive and secret society that will only let Link join if he can find the five rascals all around Clock Town. The quest for the Bomber's Notebook will only initiate if Link is in Hylian form. He will then be given a passcode consisting of numbers 1 through 5 that gives him access to the Bombers' hideout, also known as the Astral Observatory.
