Moon

I love to play games,

By transforming, I don't always look the same.

Sometimes, I'm round.

With lofty clouds that surround.

I am a silver sphere.

I am following you everywhere.

Sometimes you can see half of me,

Other times I'm full, you see.

Sometimes I'm a crescent,

Turning the sky beautiful and fluorescent,

Sometimes I smile,

Then I hide for a while,

Sometimes, I surprise you.

Peek-a-boo!

Look up at the sky,

Past the birds and the flies,

For my illuminating light,

You can see me right?

Tell me, tell me, what shape do I have?
