prepare yourself for the end

On the day when light gives its last stand
Darkness comes to conquer the land
Black clouds will cover all of the sky
The coldness comes and the end will be nigh
You will most certainly turn, transform into a fiend
You have only moments to get your soul cleaned
To survive the end you just have one chance
Buy Mr Cleaner and harden your stance
With the right cleaner, you can smell spring and light
That will give you the edge you will need for this fight
