Go where there is one block and then two blocks together, just like at the beginning of the level. Get on the last of those blocks and jump to see a vine. Get the block with a extra life and a few coins there, then go to the part where there are three pairs of three blocks each. Jump in between the bottom pairs and three invisible blocks will form. Jump on them and hit the third block in the topmost pair to make a vine will appear, which takes you to a red ring for a power-up. Continue until you reach the midway point. When you reach a Goomba and three blocks, go on the second block and jump. You will receive a Starman.
