Erosion in mountains, it does not break blocks.

So, lets talk erosion. Today we'll talk about Erosion in mountains, to connect caves to mountains. This will also make mountains and caves much more beautiful.  Lets get into it! So, when a mountain is generated touching a ocean, it will change the terrain around it. It will make a large hole, with larger spaghetti caves to connect it to cheese caves! In these caves, the water has burst in, changing the larger spaghetti's cave look. Depending on the caves generation and the ocean its touching, it will change the caves local water level. The oceans height will be put into the cave, but the caves depth will not change. So areas of the cave will be filled, depending on where the hole is located! They may also generate when touching massive lakes or rivers, but only very VERY rarely. In these caves bigger spaghetti caves, you will get a new effect called "Calm". This will make all monster's ignore you, but also debuff you in some ways. It will not let you sprint or swim. Neither will it let you attack. When in a boat, you will only be able to go at a slow speed. This will make a calming experience, to slow players but also make them look at the beauty of minecraft. You will lose this effect once leaving the cave, though.
