He's a Wandering Planet

Here comes a bubble
Floating in the thin air
Suddenly it disappear
Where did its molecules have gone?

There is a leaf
Falling from the treetop
Down and down it goes
And then shamelessly hit the ground.

Now here he is
Continuing his journey
Subsequent to this star
His precious little star, his treasure.

He is like a sailor.
Going after his north star
Now it has moved out
Where is he supposed to be going.

He cried in agony, a big torment
Cried hard for his lost
And was planning to end up his journey
He throws away his paddle.

He saw an elliptical orbit, come near to it
And then he had known
He should follow no star
For he is a wandering planet.
