 1205/-250/560 (lava)

 860/-235/520 (lava)

 740/-185/580 (mushroom)

I checked out the coordinates you gave me for the three entrances. The cave at  1205/-250/560 is nowhere near the other two and does not connect to them. It's just a small cave not worth any exploration. I've mapped out the all the coral and lava caves by laying pipe through them and viewing them through the cyclops canopy. Here is the Lava Cave in question.

Lava-Coral Cave

Here is where I started laying pipe in the coral cave. This is the entrance at  740/-185/580. http://i.imgur.com/rf2LTRQ.jpg

It continues underground connecting to the lava cave. http://i.imgur.com/jVFuq7t.jpg

And exits in the koosh zone at  860/-235/520. http://i.imgur.com/eN73R7f.jpg

It has no entrance at  1205/-250/560.
