Nokonoko is the Japanese name commonly used for Koopa Troopas, the recurring turtle-like enemies from the Super Mario series. They appear in many games as foot soldiers of Bowser’s forces, often walking along platforms and retreating into their shells when attacked. Depending on the game, they may serve as simple obstacles, be used for platforming mechanics, or appear in special roles and variants. They are not usually a single unique character, but rather a species or enemy type in the Mario universe.
