Bomber's Notebook

The Bomber's Notebook is a quest item obtained in The Legend of Zelda: Majora's Mask. The Bombers Secret Society of Justice award it to Link when he joins the group (in the original and all remakes except The Legend of Zelda: Majora's Mask 3D). Inside the notebook is a list of notable characters that Link can help throughout the game. It shows all the times the characters are available to talk to, as well as any rewards or important information Link has received about them.
