In the garden at night when the aliens are sleeping and the blades of grass are glistening in my back yard, there can be seen zombie flowers.
They only come out at night because they are zombies.
Zombies natural predators are aliens and aliens generally infiltrate the human race by pretending to be human and so they sleep during the night with their human husbands and wives who are none the wiser of the existance of the aliens, or the zombie flowers.
Or something like that.
Here, have a zombie flower, they taste like chicken. Doesn’t everything these days?
Zombie flowers - they taste like chicken only lethal.
