Toad, also known as Kinopio in Japan, is a fictional humanoid mushroom that is both a single character and the collective name of the "Mushroom People" found in the Mushroom Kingdom. The Toad speciesfirst appeared in Super Mario Bros. as seven guards that serve Princess Peach, called Mushroom Retainers. In games prior to Paper Mario, which features an entire race of Toad inhabiting Toad Town, the capital of the Mushroom Kingdom, manuals referred to them as Mushroom People, but they were always referred to as Kinopio in Japanese languages.
As a singular character, Toad is known for being the long time servant and attendant of Princess Peach. He constantly tries to protect her; however, he prominently fails almost every time during the events of her kidnapping. Despite his cowardice, Toad is notable for being one of the few characters who help the Mario Bros. through a variety of different ways throughout their adventures. Toad has even made his own fair share of heroic contributions as seen in games such as in Wario's Woods (a game that features Toad himself as the main hero) and Super Mario Bros. 2.
