From Nitendo's classic video game comes the Super Mario Brothers collection of clip on keychains. Bananas are common tropical fruit from the Mario, Yoshi, and Donkey Kong franchises. They are based on the nonfictional fruit of the same name, specifically, the cavendish banana. They grow in many tropical islands of the planet, such as on Yoshi's Island and Isle Delfino. Bananas are widely used as food due to their restorative properties and Banana Peels are also used as an offensive weapon in sports competitions such as the Mario Kart series.
