I love early oddball Mario games where these characters are not firmly established entities yet so Nintendo's just doing whatever. Nothing in this puzzle game became concrete Wario lore at all and I kinda dig it? His main enemy is Toad. He conquered a forest using black magic. He has a necromancer, a mermaid, and a dragon as evil minions. At one point he says "I have exceptional strength, power, wit, and charisma!" after using a bike pump to inflate himself. Birdo is there.
