Toad
Toads are the servants at Princess Peach’s Castle in the Mushroom Kingdom. Toads give off a strong sense of peace, but are no strangers to adventure and kart racing. Most feature white heads with red polka dots, but there are other types as well, including Captain Toad, self-proclaimed leader of the Toad Brigade.
