Custom Parts are hidden items that can be used to create a custom Bomberman in battle mode. They appear in the games Bomberman 64 and Bomberman 64: The Second Attack! There are four types of items that can be found that include the head, body, arms, and legs. Most of the items create silly costumes that add an extra element of creativity to the Bomberman games.
- In Bomberman 64, if a Bomberman wins a round in a battle game while wearing a custom part, they will say "Yay!" at the screen.
