Instructions
Keep your distance when trying to take down a Tanker Beetleworx. If you get too close, they will punch you. They also shoot paint and paint thinner from their guns, so jump to avoid those attacks.
Run in a wide circle around the Tanker Beetleworx. Shoot paint thinner at the apple body as you run. Keep shooting until the body disappears and reveals the robot underneath the armor.
Look for the green, blinking button near the top of the robot. Run up to the Tanker Beetleworx, jump and perform the spin attack by shaking the Wiimote. The body armor will come back after you attack, so repeat the process until the Tanker Beetleworx is destroyed.
