Oh, you must come to the park,

So we can have some fun.

You must come to the park today,

And play games in the sun.

Oh, we mustn’t walk on the path,

And we mustn’t climb the trees.

We must put litter in the bin,

Let's keep the park clean, pleas.

Oh, we must be very good,

And we mustn’t pick the flowers.

But  we can have a  lot of  fun,

And play for hours and hours.
