How do I make sure the lighthouse keepers are distracted?

They do look pretty distracted, to be honest.

But it's best to make sure.

Why not try talking to them?

With the storm so noisy, you might need to make some big noise yourself.

Luckily you have just the right tool for that.

Use the AIRHORN on the window/keepers.

Now you can talk to them. Or at least the one who will answer.

So he'll go to the lighthouse as soon as he finds his boot.

It would be in our best interests that he doesn't find it any time soon, then.

Can you maybe see it anywhere?

Just take that boot with you. He'll get it back eventually.
