A song about a mushroom

Lyrics:
Underground Underground
Underneath the dirt I grow
Underneath Underneath
Where people place their feet
I am small
I stand tall
Where the shade hides me
They don't see
They don't see
But I am here and growing

Underground Underground
Do they not see me right here?
Underneath Underneath
I will make them wake
I am small
After all
But things will change soon
They can't see
They can't see
But my roots dig deeply


I'll over take everything
They'll never see it coming
I'll over take this place yet
What roots touch will be mine

Underground Underground
Can you see me spewing now
Underneath Underneath
Spores for to slew in
I will grow
Bigger now
Shade cannot hide me
They will see
They will see
That I am here and growing


I'll over take everything
They'll never see it coming
I'll over take this place yet
What roots touch will be mine

Above Ground Above Ground
Their eyes are now glowing red
Infected Infectee
Mind is now melting
I have grown
Bigger still
Eyes are upon me
They can see
They can see
What I am now conducting


I've over taken everything
They never saw it coming
I've over taken this place now
What roots touch are now mine

I'll over take everything
They'll never see it coming
I'll over take this place yet
What roots touch will be mine
