Cephalic Carnage

Mired in a spindle bound
Killing something new
Living underground
I crawl everywhere, eradicating everything I purge
I got my new blood
My skin is growing back
Hide amongst the plants
The new brain is mad
My friends don't like the way I look
Soon they'll be a feast for me
And we'll have a life of bland
Impregnate my arachnid bride
Systematically weaving to survive
Victims fly into our traps
Frantic they try to rip away
Imminent paralysis
Fangs pierce insect flesh
Toxified they now convulse
