Amazing Alleycat

The changing shape of land

Causes humans to scour the earth

Heroes aren’t just for children

That’s what they all say

Though they maybe small

A blazing will and a new era prove all

When the Chips are down and the homework is due….so?

Picking up all our broken will and forging it into a weapon…and?

Correcting life’s up and downs…

We need an AMAZING ALLEYCAT a placebo to believe in

Though the future is far away

He’ll stretch his hands and cover the gap
