Sense Sonnet - Chiller

Surprise Gift

This morning, I find at my door
A large tall, potted cactus plant.
The unsigned card does thank me for
Being such a wonderful aunt.
Not an aunt at all, I do guess,
As I pull the cactus inside,
That it's come to the wrong address.
I hear a strange noise amplified.
The cactus does shiver and shake.
Suddenly, the whole thing does burst.
Horror grips me. It's no mistake.
All has gone from bad to worst.

Thousands of them swarm from there.
Scorpions are everywhere.
