Walking City

I was born in walking city
Walking city number 27
I learned at the school
Humans were living on the land a long time ago

My dad is an inspector of messages from insects
Now humans lost how to get that
He gave me a butterfly, it's tiger butterfly
And she's so beautiful

(chorus)
717,her name is it
Only one thing I know, she left a strong chain in me (2x)

Trees in forest lost leaves from acid rain
I heard there were people,who had 3 golden lines on the side of there arms
Tried to put leaves back on the trees
But the damage was pretty big

Then humans started to build walking cities
To keep oxygen inside
According to my dad
Insects have important role between humans and trees

(chorus)
Now humans learned from insects
That leaves are the ears of trees
But trees in forest lost leaves
And the ability of hearing the messages from insects
They lost how to protect themselves
Scientists and inspectors have been trying to interpret the meaning of communication signal,717
From insects
