It flutters around.

It flutters around and kept making the sound, that sounded like nothing.

Those butterfly flew around freely, some in a garden, some in a building 

and some flew frantically in someone's stomach. 

I saw a white butterfly with black little spots,

I caught it with my bare hands, 

and I swallowed it. 

So, now I have a butterfly in my stomach. 

Does it flutter around in there?

I guess so and if only I have the guts to kill them, I will do so but sadly, no. 

I love 'em butterfly.
