Bomb Bell

The Bomb Bell is a type of Nobody Ship that can be found on various Gummi Ship missions. When they appear, they hover on screen for a few seconds, then move in froward before detonating. There are also glowing Red and Gold versions that drop treasures when defeated. Interesting to Note is that a silver version of this Nobody appears in the Xemnas final battles, first when destroying the generators in the first battle, and then as random enemies in the Dragoon Ship battle.
