Junkyard Layout.
You must collect 6 Bikeparts Strewn around the level and take them back to the machine.
You are in a cave, inside the hill of the junkyard, there is an elaborate arrangement of machines and cables for transporting junk, etc. Green slime is toxic and will hurt you/ kill you if you fall in it.

junk throwing enemy

might add a falling section - a door that you go into from the top left of the main section - you simply fall for a few seconds controlling left and right collecting fish. Otherwise layout is complete.
