What nice boys!! The innskeepers will be ecstatic that these two stayed behind to help with the gruntwork and will direct them to a ladder and a very tall lighthouse that's cracking and faded and needs a fresh coat of paint and sealant. The blue that was collected matches the faded blue of the lighthouse and the boys will need to clean up, paint and repaint.

As for the light, they can ask around the supply shops for lights big enough for the lighthouse and it's up to them to figure out how to get in and up to the top to replace it. They will have several stairs to climb while carrying their equipment, and they'll have a handful of pesky seagulls around the lighthouse both while painting and replacing the bulb, but they should be successful. Just in time, too. The innskeepers will congratulate and thank them for their work, but they will also mention that there's an even bigger storm coming soon. It's time to batten down the hatches and make sure the lighthouse works by testing the bulbs before the rain hits.
