Bomb Boo

"When they hit something, they go BOOM!"

- Mailtoad

Bomb Boos are an explosive, black-colored variety of the Boos that debuted in Super Mario Galaxy. They later make a reappearance in the Mario & Luigi series during the Minion side modes.

Super Mario Galaxy
In Super Mario Galaxy, Bomb Boos only appear in the Ghostly Galaxy during the missions Beware of Bouldergeist and Bouldergeist's Daredevil Run, where they are necessary to defeat Bouldergeist. Bomb Boos float lazily back and forth, exploding after some time, but they do move towards Mario or Luigi if either of the Bros. get close to them. If the player spins near one, Mario or Luigi will grab its tongue, and continuing to spin will swing the Boo around until it hits something or they eventually lose their grip.

Up to six Bomb Boos can be held at once. If the player holds it for too long, it will begin to flash red and explode soon after, damaging Mario or Luigi.

Super Mario Galaxy 2
In Super Mario Galaxy 2, Bouldergeist re-appears, along with four other Super Mario Galaxy bosses, in the Boss Blitz Galaxy. Because of Bouldergeist's reappearance, Bomb Boos make a comeback so Mario can damage the boss in the same way as he did in the previous game.

Mario & Luigi: Superstar Saga + Bowser's Minions
Bomb Boos reappear in Mario & Luigi: Superstar Saga + Bowser's Minions as both enemies and controllable units in the new Minion Quest: The Search for Bowser mode. Bomb Boos are flying troopers, and attack by running into enemies. Their special attack, Kaboom Blast, allows them to explode on an enemy. Bomb Boos are strong against Ice Snifits.

Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey
Bomb Boos also reappear in Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey, where they are both enemies and allies in the Bowser Jr.'s Journey mode. They serve the same role as they did in Minion Quest. Additionally, a Bomb Boo appears as a figurine on a shelf inside the Tower of Yikk.

Dr. Mario World
Bomb Boo makes an appearance in Dr. Mario World as an assistant doctor. When the Bomb Boo has a skill level of 1, it will grant the player a 50% chance of having a half-full skill meter at the start of a stage and a 5% chance of receiving three extra capsules when the players amount of remaining capsuals equals three. As the Bomb Boo levels up, the percentages for each boost increases by 10% and 5% respectively, for a maximum of 90% and 25% at skill level 5.
