The light that illuminates the way home

Exploration Stage: Itallian Patio
From: Spirit of Spring
Description: I haven't seen those lovely birds for days now! I wonder if they got lost in the fog that covers the sky? I know how to help them get back to the city. But it would be easier if you helped me. Will you help me find the light buoys?
Completed: You found the light buoy! Thank you so much. The light from the buoy, shining brightly enough to be seen from the heavens, should be able to guide the birds in the right direction when they pass overhead.
