Spike Cannon

Spike Cannons are enemies in the Game Boy Advance game Wario Land 4. They only appear in the level Pinball Zone, which is situated in the Ruby Passage. Spike Cannons come in red, blue and green, with different expressions on their faces. They are found in the areas with wire mesh that Wario must climb to progress in the level. The Spike Cannons shoot spiked balls in an attempt to harm Wario. The top of the Spike Cannon act as a platform that Wario can stand on, but he cannot stay for very long or else he will take damage. They cannot be defeated.

There are also Spike Duds, which are very similar to Spike Cannons in regards to appearance, but they do not shoot any spike balls and they are safe to stand on.
