Every rock destroyed has a chance to spawn a ladder, becoming more likely as there are fewer rocks remaining. If this is successful, a ladder will spawn and prevent further ladders spawning from rocks. (In contrast, in the [[Skull Cavern]], there is a 20% chance that a shaft will spawn instead of a ladder, and this does not prevent further ladders/shafts spawning from rocks.) | Every rock destroyed has a chance to spawn a ladder, becoming more likely as there are fewer rocks remaining.
