Do they need those cannonballs? Harlock hadn't mentioned anything about them. But they might be useful, so...better picked them up anyway.

So while Harlock is carefully wrapping the body, and pulling it away from the body...Link is swimming around the deck, picking up the cannonballs. Each one disappears into his korok-enchanted pack...which doesn't appear to be getting any heavier.

He also finds a crab. That goes into the pack too.
