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
