My Piggy Bank

I've been busy with my crayons

And it took a real long time

I wrote a special message

On my paper. It's a sign

You see, I have a Piggy bank

He stands up on a shelf

The only money in him

Is what I put in myself

But thing will be much different

Once the sign goes there, you'll see

My Piggy bank will overflow

'Cause my sign says , please feed me'
