The Minish Cap

The evil sorcerer Vaati has broken the legendary Picori Blade and unleashed monsters into the world. Only the fabled Picori tribe can reforge the sword, but there’s a problem: the Picori only show themselves to children. A young boy named Link, the blacksmith’s apprentice, is tasked with searching the Minish Woods to find the Picori and reforge the blade.
