You can duck-slide under it from the top of the center platform, but it's tricky. Just above the pipe back up, there's a power up block, but it's hard to hit unless you're small. If you take the second pipe down you can reach a coin basement. There are a couple of piranha plants past here. If you can't find it, don't obsess over it, it isn't in all revisions. In some versions of the game (like the original Duck Hunt combo cart) there is a hidden extra life block over the third block. Past this, there is a row of four question blocks. You'll pass a group of four question blocks (they're just coins, but they're a good way to get high enough to kill Lakitu. Having Flower Power really makes things easier because of all the spinies. There's a power up right at the beginning. You can also kill Lakitu at high points, but he'll respawn before long. The easiest way to beat the stage is to hold the run button and dash straight through. If you took the warp in 1-2 like most lazy folks do, you'll find yourself here.
