A green spy was following a blue spy.
Followed by a night sky.
Followed by a fat lie.
Followed by a cherry pie.
Followed by a striped tie.
Followed by a black eye.
Followed by a butterfly.
Followed by a day in July.
Followed by a magpie.
Followed by a deep sigh.
Followed by a bye-bye.
Followed by a good cry.
Followed by a blue spy.
