Cowsss.

Okay, I'll write about a cow,
but that's so commonplace.
I think I'll have to make her be...
a cow from outer space!

My cow will need a helmet
and a space suit and a ship.
Of course, she'll keep a blaster
in the holster on her hip.

She'll hurtle through the galaxy
on meteoric flights
to battle monkey aliens
in huge karate fights.

She'll duel with laser sabers
while avoiding lava spray
to vanquish evil emperors
and always save the day.
