Gunner Guy

The Gunner Guy is a military Snifit unique to the Koopa Troop. They are used to guard important locations, such as Bowser's Castle. Gunner Guys appear only in Mario & Luigi: Superstar Saga. Because of its very long snout which serves as a gun, a Gunner Guy can hardly move by itself. So, a Shy Guy clad in army camouflage will show up in order to help him during battle. The Shy Guy will push the Gunner Guy up to its target before firing, giving the Mario Bros. less time to react. If the Shy Guy simply pushes the Gunner Guy, the latter will fire a cannonball which will fall onto the ground and roll very slowly. If the Shy Guy hops before the attack, the Gunner Guy will fire a quick projectile that will fly toward the player. Both attacks can be dodged by jumping.

Trivia

 * The Shy Guys who help Gunner Guys look like the Shy Rangers from Super Mario RPG: Legend of the Seven Stars. It is unknown whether the two species are related.
 * Despite the fact that Gunner Guys have 'Guy' in their name, they are considered a Snifit sub-species.
