Now, I've always been a fan of Wario Land, but my understanding of the series recently changed when I realized that the whole series is Nintendo's Self-Parody of Super Mario Bros., in the form of a Fractured Fairy Tale. The kind, heroic and friendly Mario is replaced with a greedy, selfish, brute whose appearance is an exaggeration of all of Mario's features (big nose, curly mustashe, ect.) The enemies are more evil, and while Mario journeys across the Mushroom Kingdom to resuce Princess Peach and save the world, Wario only does heroic deeds when he sees an oppurtunity to get rich doing so. Wario does things such as set himself on fire and break through stone with his head to progress, which is quite different than Mario's athleticism and jumping on top of enemies. Brilliant! -Dr Furball
I used to dislike Wario's toilet humour. Then I realized it: Mario likes MUshrooms and wario likes WAshrooms.
The reason Wario is slower than Mario is not only because he is fatter, but because his games should be played slower with more focus on exploration.
Why are their Wario toys in the Topaz Passage level in Wario Land 4? Because in the best ending of Wario Land: Super Mario Land 3 Captain Syrup's Genie gave Wario a whole Wario planet so obviously most toys on that planet would feature Wario! The planet even has a Greedville which is where the intro starts in Wario Land 4 which is seen in greater detail on the Wario Land 4 website!
The only way to get a game over in Wario Land 3 is to lose to the final boss. Isn't Wario supposed to be invincible in that game? Ah, but the game over isn't because of Wario dying, but because of him failing to stop Rudy from taking over both worlds.
Notice how the Old Man in the ending of 3 wears purple robes with some slight yellow lining, uses magic, flashes light-blue when using it and his pose when he is sending Wario back to his world. He is the uncursed form of Wolfenboss, who also wears a very similarly coloured robe, is the only enemy in the game who uses magic, flashes light-blue when he is damaged and defeated and makes a very similar pose when attacking to the one the Old Man makes when sending Wario back to his world. It also explains why Wolfenboss is so hard compared to the other bosses: he's the cursed elder of the Music Box world.
Oh boy, that endless moneybag in Wario Land: Shake It!/The Shake Dimension is going to screw up the economy. Even if those coins aren't accepted as money anywhere, they could still be melted down for gold (or whatever metal they're made of).
Most enemies in 3 (possibly all but the final boss and Mad Scienstein) are actually human villagers cursed by Rudy the Clown. Consider how many of them you crushed, burned, drowned, etc. before knowing this.
In Wario Land 2 why did the pirates decide to leave behind an annoyingly loud alarm clock to wake Wario up? Why didn't they just steal the treasure, leave the tap running and just leave with the treasure before Wario woke up and discovered he had been robbed long after the pirates had stolen it? Not to mention the clock was a massive clue for Wario to who was behind the robbery of his castle due the clock having a skull on it which is the pirates' main insignia. Seriously were the pirates just asking Wario to come and give chase after them?
In the first chapter of Wario Land 2, why does Wario have to recover coins and treasure from inside his own castle?
Enemies will steal the loot if he doesn't take it? After all, doesn't he leave the castle after Chapter 1? Better to take it with you, especially if you have bottomless pockets.
What's stopping Wario from going to the river before getting the second music box?
