The Batman Rhyme

Whose Batman is that?
I don't  think I know.
Its owner is quite happy though.
Full of joy.
Like a vivid sky with a rainbow.
I see him laugh. I say Hello.

He gives his batman a tiny shake,
And keeps chuckling till his tummy aches.
The only other sounds are that of distant waves
And birds awake.

The Batman is little, secretive and deep.
That is because he has promised to keep.
After some cake and a lot of sleep,
Sweet dreams come to him cheap.

He rises from his gentle bed
With thoughts of kittens in his head,
He eats a lot of jam with little bread,
Starts getting ready for the day ahead.
