The Toads are a species that Princess Peach protects and rules.
Relationship with Princess PeachEdit
The Toads love and respect Peach and do what they can to protect her (Although often failing) A prime example of this is in the Super Smash Bros. series, where Peach pulls outa Toad to shield her from attacks.
Super Mario Bros.Edit
In the original Super Mario Bros. once Mario has cleared a castle, he will meet a Toad that tells him :'Thank you Mario, but our Princess is in another castle'. Later in Super Mario Bros. Wii, two Toads would become playable characters in the Multiplayer Mode, and assit Mario and Luigi in saving Peach.
