Course layout
The level starts out with a Yoshi hatching from his Egg and a Lava Bubble on a track to a Bob-omb surrounded by Hard Blocks. After the Bob-omb explodes, if the player jumps to where the Bob-omb was, he or she hits a Hidden Block containing a Super Mushroom on a Fire Flower. In the next area, there is another Bob-omb surrounded by Hard Blocks, but this has a Fire Piranha Plant and a Big Venus Fire Trap above and a long row of Spike Traps below. After this are three Bob-ombs surrounded by Hard Blocks with three Bill Blasters to the left that shot Zigzag Lava Bubbles. There is also an opening at the top guarded by a Big Piranha Plant. Below are Spike Traps and a Note Block to get back above the bridge from below. On the bottom right of the area, there is a Pipe that gives Yoshi Eggs and a One-Way Wall blocking anyone going further right on this path. Above the Pipe is a Conveyor Belt used to get Yoshi to Lifts, which will bring him to an area where Mario wall jumps to. Above the Lifts, there is a ? Block containing a 1-Up Mushroom. To the left are nine Bob-ombs surrounded by Hard Block, a Burner, and three Grinders on tracks, which the last can be used to go through the area without destroying any Bob-ombs. Below is a Conveyor Belt which will take the player back to the Pipe. On the right, however, are four regular sized Dry Bones followed by five Big Dry Bones. The next area is three bridges that the player must travel right, left, right on and the area has seven Winged Hammer Bros., two Fire Bars, and a Bob-omb surrounded by Hard Blocks, which guards several coins and a ? Block containing a Super Star. After getting past the Hammer Bros., there is a hallway then a battle against Bowser with three Fire Bars in front of him. The Axe is on the other side of Bowser.
