This stage has obviously earned its name from the large vat of radiactive waste that sits front and center at the bottom of the stage. Contact with the contents is lethal. This wouldn't be so troublesome if the jumps in the stage weren't so precarious. This stage also features some of the most difficult leaps found in the game.
From your starting point in the lower left corner, you will jump from island to island to reach the center of the stage. Clearing the center and the upper right corner of the stage is a simple matter compared to the remainder. To reach the upper left corner, you will need to board the tiny floating platform and ride it across the stage, jumping for the ledge when you get close enough. Then you must ride the platform to get back. When you are finished with everything else, you can complete the lower right corner, it is safest to drop above the tea cup, to the ledge below. This is a one way trip, so only take it when the rest of the stage is complete. Now you can finish off the remaining islands.
