What I'd bring to an island

"What I'd bring to an island"

I was stuck on an island

and could bring just one thing.  

I took with me a Zombie Apocalypse survival kit

because here’s just the thing

When I started packing for this most memorable trip

A thought did arise in me then that would stick

I thought to myself what dangers I might face

Lions ,tigers or bears?.. No wait.

And then to my horror the truth was so clear

neither country nor city have they appear

The reason why nobody’s seen them before is

Zombies must live on an island of course!
