Bombers Secret Society of Justice

The Bombers Secret Society of Justice is a gang of six boys who strive to do good in their home town of Clock Town in Majora's Mask. Their leader is named Jim and he wears a red bandana (whereas the rest wear a blue one, the hideout guard wearing a yellow bandana). They are good friends with the astronomer in the Astral Observatory; Link needs to befriend the gang in order to get to the observer.

The Bomber Gang befriended the Skull Kid prior to the events of Majora's Mask, but later cast him out due to his evil motives. As a result, they only allow humans to join their gang, provided that they can pass the test.

After popping the balloon Jim is firing at in North Clock Town, Link is challenged to a game of hide & seek. If he can find and catch all five Bombers participating in the challenge within the time limit, he will be awarded with a Bombers' membership (assuming he is in human form). This membership comes with the secret passcode to the Bombers' hideout and the Bombers' Notebook.

Another way to get the Bomber's notebook is to learn the passcode, rewind to the first day, go into their HQ, come back out, and speak with Jim. The Bombers greatly resemble the young boy that loitered around Kakariko's graveyard.
