Toad and the species were first seen in the game "Super Mario Bros.". Toad's design was made directly from the power up, the Super Mushroom as well as the game's general use with mushrooms. Shigeru Miyamoto, the creator of the Mario series, made a reason that Toad's creation was that of being a character that has a simplistic design; yet, still appears cute and lovely and pleases to everybody. In the game, the peaceful Toads of the Mushroom Kingdom had been turned into various objects such as bricks and pipes by the evil King Bowser; however, some of Princess Toadstool's loyal servants, known as the "Mushroom Retainers" were simply kidnapped. During the making of "New Super Mario Bros. Wii", the developers at Nintendo decided between four characters to be playable in the game: Princess Peach, Toad, Wario and Waluigi (all suggestions made by fans). Two Toads (yellow and blue) were eventually included as playable characters in "New Super Mario Bros. Wii" due to their physical similarity to Mario and Luigi.
