I like to be a jumping jack

I like to be a jumping jack
And jump out from a box.
I like to be a rocking horse
and rock and rock and rock.

I like to be a spinning top
And spin around and round.
I like to be a rubber ball
and bounce way up and down.

I like to be a big, fast train
Whose wheels fly round and round.
I like to be a pony small
And trot along the ground.

I like to be so many things-
A growly, scowly bear-
But really I'm a little child
who sits upon a chair.
