    Wario, is a portmanteau of Mario and Warui, the Japanese word for bad or evil. In English, he is very obviously just Wario with the M flipped upside down.

    The original manual for Super Mario Bros. 2 states rather clearly that Birdo is guy who thinks he is a girl. Then again, sex and gender must be a sticky subject for a species of reptile who lays eggs by spitting them like projectiles through its mouth.

Mama was a taller sprite than Imajin, who would later become Mario, though it’s unclear whether or not this eventually influenced Nintendo’s decision to increase Luigi’s height.
