List of Wario Land 4 glitches

This page lists all the glitches found in the Game Boy Advance game Wario Land 4.

The player must get into a corner which is four blocks high. Then they must then go right next to the wall, and then turn around so they'll face away. The player must jump, and then just before Wario hits the ceiling, the player should press down and forwards for a split second. Then the player has to hold forwards. To zip, the player must rapidly press while holding either left or right.

When Wario picks up an object, there is a slight chance that when the object leaves his hand (whether he throws it or drops it), something may still be in his hand, even if nothing appears to be there. Wario must throw the invisible object in order to get rid of it.

In the level Fiery Cavern, Wario is forced to hit the Frog Switch in the middle of the level during normal gameplay. This will cause the rest of that level to freeze over and everything, including the lava, will be covered in a layer of ice. However, if the player uses an Action Replay or some other game-hacking device, they can avoid hitting the Frog Switch. This will prevent the rest of that room being covered in ice. But if Wario moves on to the next room in the level, everything in that room will automatically get covered in ice anyway.

In the Golden Passage, Wario is forced to hit the Frog Switch upon entering the level. This will cause the normal Frog Switch music to play throughout the whole level. Avoiding the Frog Switch is impossible during normal gameplay, because when Wario enters the level through the Vortex, there is no time to move away from the Switch directly below. There are also invisible Frog Switch Blocks on either side of Wario that disappear when the Frog Switch is hit. However, if the player uses an Action Replay or some other game-hacking device, they can avoid hitting the Frog Switch and the usual, fast-paced music won't play. Instead, a hidden, unused soundtrack will play as the level's true theme.

During the game's development, the Frog Switch was to be placed at the beginning of the level only for the hard and S-hard game modes. It was planned that in the normal game mode, the Frog Switch was to be placed at the end of the level, in order to give the player a chance to listen to the theme. This was changed for the final game, but the hidden soundtrack was never removed from the final game.

Sometimes, but very rarely, if Wario jumps repeatedly against some blocks, he will be able to walk through them, However, he may get stuck inside the wall.
