The three pipes located throughout the stage warp to one another. You can even enter the pipe at the edge of the cliff. A piranha plant sometimes sticks its head out of the pipe. You get hurt if you touch it, but you can send it flying by attacking it.
Attack the POW Block that appears on the stage to launch all fighters on the ground. Once it’s been depleted, it reappears in one of four places on the stage a short time later.
