Snake

He came in a box

I opened the lid

I tilted it down

And down he slid

His face triangular

His mouth opened wide

A mouse walks in

And has nowhere to hide

He curls up in a ball

For how he gets his name

And I put him down

He tries to back to where he came

I open another lid

This time much bigger

And I put him in the terrarium

And he starts to slither

He finds the cave in the corner

And he peeks inside

He crawls on in

It's where he'll reside

He's home now

My new reptilian friend

Monty Python, that is

I think he's a God-send
