The lantern gets a curious look, from Link - with that concentrated beam, it's brighter than Brightblooms usually are.

But even if it's not strictly needed, Link still draws his bow - and fires off a few more Brightbloom seeds into the space, until there's no more pitch dark spaces. The lantern will still help illuminate the specifics. But this way, they'll at least be able to see the whole space better.

And with that task done, Link drops down to a lower section - to a part where there's lots of crates, broken or otherwise. What's inside those?
