This is probably a dumb question, but I just came across this rock near the portal over lake hylia, blew it up, and found this cave. I was just wondering what the heck I found? It seems like a mini version of the cave of ordeals (found that, but not NEAR ready to go through it). I still need to beat the "sand temple" actually, so I'm not too far along in the game. I'm just wondering if this cave of lake hylia is something I'm ready to take on -- but more generally, what is it?? Just a cave with pretty money inside? Honestly, I should probably just play through and find out myself :P lol Thanks!
