Big Bob-omb

Big Bob-omb is the boss of Bob-omb Battlefield, and the leader of the Bob-ombs. They are a large sphere with blue arms and legs that lead to yellow hands and feet. They have a yellow crown, white mustache and white eyes. They are defeated by being picked up from behind and being thrown. They attack by grabbing the player and throwing them. When defeated, they drop a star.

The Big Dud
In the mission where Big Bob-omb is fought, there are 2 Big Steelies rolling around the base of the mountain. After Big Bob-omb is defeated, there are 3. A Bob-omb Buddy also claims Big Bob-omb is "nothing but a big dud now" when defeated.
