Waterfall is a location in Freddi Fish 3: The Case of the Stolen Conch Shell. It is available in all versions of the storyline, but it is only important in Blue-Tailed Joie Bird's Golden Pipe storyline.
Now this is a stumper! Freddi and Luther can't get past the waterfall, but it sure looks like there's something on the other side. They can't go around it so they'll have to go through. How will they do it?
