5-1
This is the first level in World 5. It introduces the Stalking Piranha Plant and the River Piranha Plant. It contains very large Koopa Shells, some of which, Mario can enter and find secrets. While most of this level takes place on land, a portion of it it over a body of water. There are many swinging vines the player can use to travel over gaps and Stalking Piranha Plants. Fire Mario is very helpful in this level.

World 5 Ghost House
The third ghost house in the game. Common ghost house enemies can be found, including boos. It is possible to find a secret exit that will take Mario and company to the world 5 cannon. This cannon shoots Mario to world 8, Bowser's Volcano.

Enemy Course

 * Four Stalking Piranha Plants

Mario and Co. start on a plattform above four plattforms on which the Stalking Piranha Plants walk. There are moving platforms directly over them on which the players can jump on to collect the Toad Balloons. They have to be careful, though, as the Stalking Piranha Plants can still reach them with their head when they stop walking. All the player has to do is jump over them.
