This monster is nice

This monster is nice.
Sure, it has claws
and thousand eyes,
but it doesnt kill!
It munches plants
in its three jaws
and while it flys
it is harmles.
But still
you do not will
allow me to
keep it by my side,
instead you gave
it the final blow.
It didnt harm anyone!
Sure, it wasnt from here,
but I will become
its avenger and go where
it is now by
entering my dreams.
