Instructions
Walk through the Mad Doctor's attic level carefully. Look for the Beetleworx generators by locating the large bright red lights attached to them. Defeat the enemy near the generator in order to cause the machine to open, producing another Beetleworx enemy.
Walk up to the generator and wait for it to start opening the doors to produce a second Beetleworx foe. Use your Watch Sketch ability to slow time, making it easier to pinpoint an attack to the red flashing light on the generator.
Spray a continuous line of paint thinner at the center of the generator's red light. This will disintegrate the generator, destroying it. This eliminates any more Beetlworx enemies from being created.
Walk up to the second and third generators and destroy the enemy standing next to each of them. There are three generators altogether with three different enemies. The first two generators have a Sword bot and a Spinner bot. The last Beetleworx generator produces the Tanker foe.
Spray paint thinner on the final red light to destroy the Tanker generator and gain access to the Mad Doctor for a battle.
