Duckweed in the Spout

From: Detective
Description: Thank you buddy, for volunteering to help. I examined the place where one of the lion spouts was and noticed the traces of huge claws and marsh duckweed. I have a feeling that the gargoyles are involved. Let’s look for a missing spout.
Completed: Great work, buddy! I can’t stand the smell of swamp rot and I hope the Mayor finds a way to clean this spout before it’s re-installed.
