Exploration Stage: Postal Dovecote
From: Mr. Black
Description: Does it indicate where these objects came from? To me, these look particularly odd. Oh well...try to find the alarm whistle.
Completed: You found an alarm whistle. These whistles are used by collectors to keep them from getting lost in the fog. How did I know about it? I saw that Vila had one. She used to use the pigeons a lot.
