The Buggy Balls (バギー玉, Bagī Dama) are very powerful weapons used by Buggy.
These red bombs, engraved with Buggy's Jolly Roger, can create devastating explosions when fired from a cannon. Buggy claimed that these cannonballs, combined with his Cursed Fruit powers, the Chop-Chop Fruit, he and his crew can conquer the Grand Line. These balls were first used against Orange Town, two of them were enough to leave the town half-damaged. Buggy attempted a third shot directly at Monkey D. Luffy for insulting his big red nose, but Luffy deflected it with his Gum-Gum Balloon technique, destroying the pub it was fired from.
The Muggy Balls (マギー玉, Magī Dama) is a modified version of the Buggy Balls Buggy made later in Impel Down, which he compacted it into a size small enough to be concealed inside a person's body. Its appearance is a bullet-sized red sphere.
Despite its small size the Muggy Ball retains the full destructive powers of the Buggy Ball (in essence, similar to a hand grenade). This was first used against the Minotaurus, where Buggy kicked the Muggy Ball from the sleeve of his pants, and the resulting explosion injured the Jailer Beast severely, but it was still conscious and standing. In the anime, rather than kicking it from the inside of his pants, Buggy instead launched it from his shoe after a small hole opened up on the bottom of the sole. Buggy also attempted to use a Muggy Ball against Mihawk, but he managed to deflect the Muggy Ball back towards Buggy using his sword.
- In Unlimited Cruise, Buggy's special attack involves him firing three Buggy Balls at his opponents.
