· Bowser Basher: a hammer modeled after his father's fists. Used in close quarters.

· Paintbrush: BJ's main weapon. Used for slipping up enemies with wet paint or blinding them.

· Chomper Stopper/ Mega Bite: sentry turrets he and some of Bowser's minions use to defend strategic points.

· Sonic Roar- a shrill scream that stuns and damages enemies.

· Hell in a Shell: a wrist blaster forged from a Koopa shell.

· Clobber Chomper & Thwomper Stomper- hammers used by BJ and Bowser's minions designed after Chain Chomps and Thwomps.

· Fire Clown Car: BJ's main vehicle has a major upgrade. It can be fused with a Fire Flower for fireballs and a flamethrower, along with fire trails in Clown Kart mode.

· BJ's Clown Cruiser: built by BJ to accompany his father in his own Clown Cruiser. With the standard weaponry(minus the flamethrower), it also uses Banzai Bills for bombs/missiles.

· Koopa Mech: BJ's mech with the Clown Car as the cockpit with an enclosed glass shield to cover BJ. Systems include a Chain Chomp flail, a Mechakoopa deployment hatch, shoulder-mounted Bill Blasters, an ejector seat, and a hammer with his own symbol(or two).

· Fly Guy Bomb Squad: A group of Fly Guys hover in the sky holding Bob-ombs. On Bowser's or BJ's command, they release the Bob-ombs, making them fall onto enemies, vehicles or structures below. The only downside is that the Fly Guys are targets for Jet Primids and other air vehicles, meaning they must be protected until they reach their target.
