Cover Orange Level 78 walkthrough has you dropping the purple barrel on the teeter totter. This will launch your orange to its safe haven. The stormcloud just barely misses hitting your orange because the large round pegs stick out just far enough to provide the necessary rooftop. Close call, but you advance to the next stage.
