Instructions
Destroy any generator machines you can. If you helped some gremlins in the last few levels, they will come and destroy the generators for you. Spot them by looking for the red lights on top of them. These spurt out enemies, so getting rid of them is important. Use paint thinner or activate the power pads using sketches. Slow down time with the "Watch" sketch and destroy the new generator being brought out. Ignore the generator near the Mad Doctor. Return to your starting location.
Paint the translucent treasure chest, then double-jump off it up to a piece of track. Notice a steel pipe hanging down at the side of the track, and double-jump up to it. Double-jump across to the wooden planking, and then go across and jump to the planking with the blue chest sitting on it. Open it to find "Donald's Leg."
Go back to the Mad Doctor and run behind him to find a destroyed generator. Jump up to the ledge above it to find "The Mad Doctor Pod." Keep moving to the right to find a treasure chest containing a "Gold Pin." Decide which method you wish to use to defeat the doctor, depending on whether you want an extension to your paint meter or your thinner meter.
Destroy the third generator in the way you destroyed the other two if you want an extension to your thinner meter. Spray thinner at the red light on the generator to destroy it. Alternatively, you can activate the three power pads to get an extension to your paint meter. Look at the Mad Doctor and then turn to your left to find the TV-activated power pad. Find the second one on a raised platform to its right.
Drop a TV on the first power pad from a distance and then use a "Watch" sketch to slow down time. Make your way to the second power pad, and drop an anchor on it. Drop down from there and go to the end of the raised track. Jump over to the ledge with the third power pad on it. Stand on the pad to complete the stage. A piece of track drops down and completes the track. The trolley car goes down the length of the track and obliterates the final generator. Go through the projector screen to exit the level.
