Instructions
Aim at the large Tanker in front of you when the battle begins. Hold down "Z" to shoot thinner at the Tanker. Jump onto the platform where the Tanker was when it's erased.
Look across the room to see a glowing blue pressure plate. Press the directional pad to switch to the Clock sketch, which slows time. Press "-" to use the Clock sketch.
Aim at the pressure plate and use an Anvil sketch. The anvil falls from the sky and activates the pressure plate.
Go left and jump to the lower level. Use a TV sketch on the pressure plate in front of you. Jump across the gap while taking care not to fall into the thinner.
Stand on the pressure plate on the other side. This changes the direction of the train tracks. A train car crashes into the Mad Doctor's machines. This ends the battle and redeems the Mad Doctor.
