What is the definition of Melbourne Blood Cells?

"Melbourne blood cells: These little marvels of biochemistry are the unsung heroes of our city's bustling heart. They're so efficient, they could outrun the entire Melbourne Marathon and still manage to deliver oxygen to our morning coffee shop's fluorescent lights. But hey, let's not forget the occasional Melbourne blood cell decides to steal a photo op and turn our city's iconic landmarks into their own personal Instagram feed!"

Example sentence with an edge: "In Melbourne, the blood cells decided to stage a protest against the city council's decision to ban all public bike lanes, claiming they were 'unnatural' and 'causing a blood shortage.'"
