What is the definition of Collectibles Blood Cells?

Collectibles blood cells: These are the tiny, blood-sucking, bone-chilling, and utterly fascinating microscopic marvels of nature that we keep in our vaults like ancient, blood-stained relics from the apocalypse. They're like nature's own Bloodborne Carnival ride, but instead of zombies and lasers, you get a mix of old red blood cells, platelets, and maybe some haemoglobin for good measure. They're the ultimate, macabre art form of our body's blood-sucking business!

Edgy example sentence: "The detective decided to collect rare 'frozen' platelets from the ice cave of the human body, just in case the next murder mystery involves bloodless heists."
