The Goat Crusher is Karakuri Ball No. 2 from Ninpu Sentai Hurricaneger — one of the spherical capsules ejected from Senpujin's chest hatch that snap open into weapons and add-on parts. From this ball unfolds a hefty smashing hammer shaped like a goat's (ram's) head, which Senpujin takes up in hand. The Karakuri Balls are the Japanese counterpart to the "Power Spheres" seen in Power Rangers Ninja Storm.

The Goat Crusher is a specialty of Hurricane Yellow. When it strikes, the handle telescopes outward so the battering-ram head can flatten an enemy with full force. It becomes truly dangerous alongside Karakuri Ball No. 3, the Tortoise Hammer: together the two form a kendama-style pairing — Senpujin bounces the Tortoise Hammer's ball off the Goat Crusher to build up energy, then hammers it into the foe as the finisher "Goat Hammer Hurricane Comet."

For the DX toy line, Bandai released the two weapons together in 2002 as the "Karakuri Ball Series 1 – Goat Hammer Set," containing both the Goat Crusher (Ball 2) and the Tortoise Hammer (Ball 3). Just as on screen, the pieces convert from their compact ball/capsule form into the full weapons and plug into the hand of the DX Senpujin. In Power Rangers Ninja Storm the counterpart appears as a Power Sphere for the Storm Megazord — a wonderfully playful collectible barely larger than a palm, yet one that instantly gives the big robot a whole new attack mode.
