The many moods of a Spike Cannon
|First appearance||Wario Land 4 (2001)|
Spike Cannons are enemies found 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 colors, and each color of Spike Cannon features a different expressions on its face. The different colors and expressions are purely aesthetic and do not affect gameplay. Most of them are found in areas with wire mesh that Wario must climb to progress through the level. Spike Cannons eject a pair of arcing spiked balls to its left and right sides in a fixed interval. This is preceded by a flashing yellow arrow at the top of the Spike Cannon's head. Wario can stand on top of the Spike Cannons, but he will take damage from the spiked balls. Neither Spike Cannons nor the spike balls they eject can be defeated, but the spike balls will disappear upon hitting the ground.
Depending on the game mode, some Spike Cannons will be inactive and not shoot spike balls.
