he Barrel Launcher is a gun in Scribblenauts. The weapon looks like an exploding barrel with a handle, and when fired, an exploding barrel is shot out. The barrel it fires is not affected by gravity. The explosion is large and will kill most animals in one hit. When the projectile is too close to Maxwell, he will die and the gun will be destroyed. In Scribblenauts, this gun has only three shots (like most guns), but its Super Scribblenauts version has unlimited ammo like all other guns. (source)
