The Very Loooooong Cave

The Very Loooooong Cave is the fifth level of World 6 in Super Mario World 2: Yoshi's Island. The level starts out with Cyan Yoshi in a cave, when the screen will start scrolling, and forcing the player through traps like Lava, and Chomp Rocks. During the very long decent the player will encounter many Lava Drops, and Boo Guys, and need to ride a few Flatbed Ferries.

Eventually the player will wind up at an area where they need to use an Expansion Block to keep going. After that they will be in a encounter a large gap, where they need to jump along thin stone pillars, with Chomp Rocks rolling on them, trying to push the player off of them. At the end of that the player will clear the level.
