It's been a long time since we've seen a treasure hunt, and now we're back in the cave. We're not exactly sure what's going on, but we do know that there's a glowing object in the water, and that it's probably some kind of treasure--a gold--that's supposed to belong to a goddess named Nemo. Nemo's got a bunch of tiny creatures clinging to a giant anomal, and Nemo is worried that they're going to turn to gold. He's also worried that the water's getting too shallow for them to swim in, so they'll have to use their brains to find a way to turn the water into gold.
