The player starts on a plain with a Piranha Plant in a pipe to the left. Above it are two pipes each with a Venus Fire Trap, followed by a tall pipe with another Piranha Plant. Afterward are five pipes with the ones on the ends and in the air containing Piranha Plants the player has to avoid and time their jumps to. Beyond the pipe are a group of ? Blocks over some Semi-Solid Platforms, with one of the blocks containing a Super Star, and the far-left-most Brick Block in the formation ahead contains a power-up. At the next Brick Block formation is a Nipper Plant on top and the player can find a 1-Up Mushroom in one of the blocks. Next, the player will encounter a Ptooie and can find a Pink Note Block directly to the left of the hanging pipe that will send the player to Coin Heaven, and the pipe at the end will drop the player near where they left. Afterward are some more pipes (the leftmost one leading to a bonus room with a Hammer Suit) with a Ptooie and a Piranha Plant, followed by a broken bridge over a line of Munchers. Next are both a stationary and mobile Ptooies in and around pipes, followed by a Fiery Walking Piranha and a Nipper Plant on two rows of blocks before the goal.
