DAVE THE DIVER, How to get sea grapes and white spotted jellyfish[Limestone cave]

Quick guide because i found it 1 time and then forgot where it was the cave xd

man... that cave is pretty hard to find.

Something I noticed is that some story quests (e.g. the one where you need to find a sunk boat) changes the map spawning completely. While I had that quest, I could not find the limestone cave, despite having the VIP quest for it. As soon as I finished the story quest, the limestone cave spawned on my next dive, and I could finish the VIP event.

My limestone caves never seam to have the jelly fish or sea grapes. I just got to the day vincent the gourmet is coming. Will it only spawn after that?

You can also get it from gumo seaweed farm

Can I use a tranquillizer gun instead?
