Yoshi is a dinosaur, and one of the heroes of the Mushroom Kingdom. Like all heroes, Yoshi has a role. To stop Bowser and rescue the princess. Like Mario and Luigi have Peach and Daisy, Yoshi has Rosalina. Yoshi first met her during his, Mario, and Lugi's trek through outer space, with the help of the Lumas, star children that are loyal to their mother, Rosalina. Ever since rescuing her from Kamek the Magikoopa, Yoshi and Rosalina have been good friends. Possibly further than that, if you can believe it. Yoshi has the power to spread love and friendship across the land, he also has the power of rainbows to do much more than create a sunny day. It is also believed Yoshi controls the weather, depending on his mood. If Yoshi gets depressed, there's gonna be a storm warning. But if Yoshi is happy or higher than what happy can be, the sun shines ever so brightly. As a young dino, Yoshi has been good friends with Mario, Luigi, Peach, and Toad. Participating in events, such as golf, tennis, parties, and racing. He also has a sister named Birdo, a female dinosaur, who he helped in her engagement to Nabbit the Rabbit. In the face of danger, Yoshi will be there to help his friends.
