In only one week time, those mushrooms have shrunk into a size so small that I am not in a good position to photograph them from an ant's view. This chances me to go aerial, and discover the descending of many parachutes.
This is a carnival rather than a declaration of war.
Each of the parachutes looks so exact in pattern, which resembles the result of copy and paste and resize that have happened in mid-air.
The landings are perfect with zero horizontal speed and no stumbling forward.
Oh yes, they celebrate without "whisper" of cheers.
Because mushrooms are cool.
