The Legend of Zelda: Majora's Mask/Join the Bombers Gang

Requirements

 * Bombers Gang Password

Rewards

 * Bombers' Notebook

What to Do
Begin by playing the Hide and Seek game with the Bombers Gang, by first popping the balloon in North Clock Town. Find their locations (See Prologue for more info). When you find all the Bombers as Human Link, they give you their password (which you already know & if you don't know the password,it's not really possible to tell you, as it is different for every game), and the Bombers Notebook, which shows the time and password for entry. It also records the troubled lives you help out.

An alternate method is to use the password you learned previously to get into the Bomber's Hideout as Human Link. When you leave, you will be given the Bomber's Notebook.
