Luca searches through the cave, but he finds nothing of use. He pops back out of it, snaking across the bottom of the sea, his coloration and the gentle movements of the kelp-like fins on top of his head helping him blend in with his surroundings while he searches for another underwater cave. After a bit, he pops back down into another opening and finds that the tunnels under here are a bit more extensive. He continues his search, feeling his way along the walls.
