I'm not really good at poetry. This was my second attempt at it so that's why it's not too good.

There was a little girl

Who found a big pearl

She kept it in her coat pocket

But it fell and made a racket

Everyone ran after it

While the girl made a fit.

The next day at school

Matt had something cool

It was the pearl, big and shiny

It made the rocks look teeny tiny

And that's how the girl

Lost her precious pearl.
