Furizō[1] are large mechanical spheres found in Mario's castle in Super Mario Land 2: 6 Golden Coins. They have four constantly-retracting spikes, though this does not affect the area of damage whatsoever. They come in two sizes, which according to the official artwork, are two different colors. They move back and forth in a pendulum-like arc to damage the player, and are completely invincible.
