Mrs.Cow, young calf is weak
Too hungry to be at heart ease
The farmer,
He drain your breast
No milk, No drop, No moo
No mew, No bleat, No bark
Will comfort your child

I’m Oxen
Alexander is wrong
I will till the earth no more
Alexander is but a man
Man is a thankless animal
And you must not let him milk you
We too are hungry
One day, we'll run man and his allies
Upon the face of the earth

Freedom will be given a chance
It will echoes to the end of the earth
Then, we’ll pay man in his own coin
For man is a tyrant

Matthias Pantaleon
