The Giant Turtle Robot is the boss of the second Wily Stage. He spits flames that can damage and stun you (like Turbo Man's Scorch Wheel), charge at you while in his shell, and lift off to send mini-turtles at you. For the large turtle, hit his head with Wild Coil. For the mini-turtles, the best bet is with Slash Claw.
