"Mini Marios (originally styled as Mini-Marios) are energetic Mario toys sold by the Mario Toy Company. They first appear in Mario vs. Donkey Kong and have appeared in all of the installments of the Mario vs. Donkey Kong series. Mini Mario is voiced by Charles Martinet in all games; they sound similar to Mario, but higher-pitched similar to Baby Mario and with a robotic undertones. The hands of Mini Marios resemble, and are likely designed after those of Lego minifigures."
