Block containing a power-up that the player has to kick a Koopa Shell into. Afterward are some waterfalls the player can swim up to reach a secret area in the Warp Pipe to the far right, where two 1-Up Mushrooms can be found, along with some Big Berthas. Beyond the waterfalls are a Grand Goomba, a Colossal Koopa Paratroopa, and a Mega ? Block containing a power-up.
