Yonder was born on Yoshi's Island. As a child, he loved to go exploring the island and all its environments. It was while exploring the island that he found the legendary and rare Mystic Fruit, which is said to grow every 100 years and lasts only a few days. When he ate it, it gave him the power to gain unique abilities by touching certain items or enemies with his tounge, similar to Kirby. When he got older, he moved to Toad Town, as he wanted to experience more of the world and felt he couldn't on the remote island. He now uses his abilities to aid the Mushroom Kingdom in times of need or when others are in danger.
