Bird Invasion

Exploration Stage: Post Office
From: Mr. Black
Description: There you are! The fog got completely out of hand and I need your help. Overnight, a bird nest materialized under my office's ceiling, can you imagine that? Life-sized, with birds and eggs. Help me take it off.
Completed: Hmm, if I didn't know what the fog is capable of, I'd think that this is a real nest. All right, you can move it to a tree. Let's observe what happens.
