Once upon a time
there was a bird and the bird sang.

Once upon a time
there was a wolf and it howled.

Once upon a time
there was a laughing orangutan

Once upon a time
there was a human and it spoke.

Once upon a time
a human killed a bird.

Once upon a time
a human killed a wolf.

Once upon a time
an orangutan was killed.

Once upon a time
a human killed a human.

Once upon a time
the only singing, laughing and howling may be from a human.

Once upon a time
no one speaks.

Once upon a time
there are no animal sounds.
